Recent nodejs node.js Security Vulnerabilities

A command inject vulnerability allows an attacker to perform command injection on Windows applications

CVE-2024-3566 9.8 - Critical - April 10, 2024

A command inject vulnerability allows an attacker to perform command injection on Windows applications that indirectly depend on the CreateProcess function when the specific conditions are satisfied.

Command Injection

On Linux

CVE-2024-21892 7.8 - High - February 20, 2024

On Linux, Node.js ignores certain environment variables if those may have been set by an unprivileged user while the process is running with elevated privileges with the only exception of CAP_NET_BIND_SERVICE. Due to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when certain other capabilities have been set. This allows unprivileged users to inject code that inherits the process's elevated privileges.

Code Injection

Node.js depends on multiple built-in utility functions to normalize paths provided to node:fs functions

CVE-2024-21891 8.8 - High - February 20, 2024

Node.js depends on multiple built-in utility functions to normalize paths provided to node:fs functions, which can be overwitten with user-defined implementations leading to filesystem permission model bypass through path traversal attack. This vulnerability affects all users using the experimental permission model in Node.js 20 and Node.js 21. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Directory traversal

The Node.js Permission Model does not clarify in the documentation that wildcards should be only used as the last character of a file path

CVE-2024-21890 6.5 - Medium - February 20, 2024

The Node.js Permission Model does not clarify in the documentation that wildcards should be only used as the last character of a file path. For example: ``` --allow-fs-read=/home/node/.ssh/*.pub ``` will ignore `pub` and give access to everything after `.ssh/`. This misleading documentation affects all users using the experimental permission model in Node.js 20 and Node.js 21. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

A vulnerability in Node.js HTTP servers

CVE-2024-22019 7.5 - High - February 20, 2024

A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an unbounded number of bytes from a single connection, exploiting the lack of limitations on chunk extension bytes. The issue can cause CPU and network bandwidth exhaustion, bypassing standard safeguards like timeouts and body size limits.

The permission model protects itself against path traversal attacks by calling path.resolve() on any paths given by the user

CVE-2024-21896 9.8 - Critical - February 20, 2024

The permission model protects itself against path traversal attacks by calling path.resolve() on any paths given by the user. If the path is to be treated as a Buffer, the implementation uses Buffer.from() to obtain a Buffer from the result of path.resolve(). By monkey-patching Buffer internals, namely, Buffer.prototype.utf8Write, the application can modify the result of path.resolve(), which leads to a path traversal vulnerability. This vulnerability affects all users using the experimental permission model in Node.js 20 and Node.js 21. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or outdated) keys

CVE-2023-30590 7.5 - High - November 28, 2023

The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or outdated) keys, that is, it only generates a private key if none has been set yet, but the function is also needed to compute the corresponding public key after calling setPrivateKey(). However, the documentation says this API call: "Generates private and public Diffie-Hellman key values". The documented behavior is very different from the actual behavior, and this difference could easily lead to security issues in applications that use these APIs as the DiffieHellman may be used as the basis for application-level security, implications are consequently broad.

When an invalid public key is used to create an x509 certificate using the crypto.X509Certificate() API a non-expect termination occurs making it susceptible to DoS attacks when the attacker could force interruptions of application processing, as the process terminates when accessing public key info of provided certificates

CVE-2023-30588 5.3 - Medium - November 28, 2023

When an invalid public key is used to create an x509 certificate using the crypto.X509Certificate() API a non-expect termination occurs making it susceptible to DoS attacks when the attacker could force interruptions of application processing, as the process terminates when accessing public key info of provided certificates from user code. The current context of the users will be gone, and that will cause a DoS scenario. This vulnerability affects all active Node.js versions v16, v18, and, v20.

A vulnerability has been identified in the Node.js (.msi version) installation process

CVE-2023-30585 7.5 - High - November 28, 2023

A vulnerability has been identified in the Node.js (.msi version) installation process, specifically affecting Windows users who install Node.js using the .msi installer. This vulnerability emerges during the repair operation, where the "msiexec.exe" process, running under the NT AUTHORITY\SYSTEM context, attempts to read the %USERPROFILE% environment variable from the current user's registry. The issue arises when the path referenced by the %USERPROFILE% environment variable does not exist. In such cases, the "msiexec.exe" process attempts to create the specified path in an unsafe manner, potentially leading to the creation of arbitrary folders in arbitrary locations. The severity of this vulnerability is heightened by the fact that the %USERPROFILE% environment variable in the Windows registry can be modified by standard (or "non-privileged") users. Consequently, unprivileged actors, including malicious entities or trojans, can manipulate the environment variable key to deceive the privileged "msiexec.exe" process. This manipulation can result in the creation of folders in unintended and potentially malicious locations. It is important to note that this vulnerability is specific to Windows users who install Node.js using the .msi installer. Users who opt for other installation methods are not affected by this particular issue.

The use of __proto__ in process.mainModule

CVE-2023-30581 7.5 - High - November 23, 2023

The use of __proto__ in process.mainModule.__proto__.require() can bypass the policy mechanism and require modules outside of the policy.json definition. This vulnerability affects all users using the experimental policy mechanism in all active release lines: v16, v18 and, v20. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js

When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application

CVE-2023-38552 7.5 - High - October 18, 2023

When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x. Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js.

Insufficient Verification of Data Authenticity

Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects

CVE-2023-39332 9.8 - Critical - October 18, 2023

Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects. In Node.js environments, the `Buffer` class extends the `Uint8Array` class. Node.js prevents path traversal through strings (see CVE-2023-30584) and `Buffer` objects (see CVE-2023-32004), but not through non-`Buffer` `Uint8Array` objects. This is distinct from CVE-2023-32004 which only referred to `Buffer` objects. However, the vulnerability follows the same pattern using `Uint8Array` instead of `Buffer`. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Directory traversal

A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6

CVE-2023-39331 7.5 - High - October 18, 2023

A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Directory traversal

The HTTP/2 protocol

CVE-2023-44487 7.5 - High - October 10, 2023

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

Resource Exhaustion

The use of the deprecated API `process.binding()` can bypass the permission model through path traversal

CVE-2023-32558 7.5 - High - September 12, 2023

The use of the deprecated API `process.binding()` can bypass the permission model through path traversal. This vulnerability affects all users using the experimental permission model in Node.js 20.x. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Directory traversal

A vulnerability has been identified in Node.js version 20, affecting users of the experimental permission model when the --

CVE-2023-32005 5.3 - Medium - September 12, 2023

A vulnerability has been identified in Node.js version 20, affecting users of the experimental permission model when the --allow-fs-read flag is used with a non-* argument. This flaw arises from an inadequate permission model that fails to restrict file stats through the `fs.statfs` API. As a result, malicious actors can retrieve stats from files that they do not have explicit read access to. This vulnerability affects all users using the experimental permission model in Node.js 20. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Incorrect Permission Assignment for Critical Resource

A privilege escalation vulnerability exists in the experimental policy mechanism in all active release lines: 16.x, 18.x and, 20.x

CVE-2023-32559 7.5 - High - August 24, 2023

A privilege escalation vulnerability exists in the experimental policy mechanism in all active release lines: 16.x, 18.x and, 20.x. The use of the deprecated API `process.binding()` can bypass the policy mechanism by requiring internal modules and eventually take advantage of `process.binding('spawn_sync')` run arbitrary code, outside of the limits defined in a `policy.json` file. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js.

The use of `Module._load()` can bypass the policy mechanism

CVE-2023-32002 9.8 - Critical - August 21, 2023

The use of `Module._load()` can bypass the policy mechanism and require modules outside of the policy.json definition for a given module. This vulnerability affects all users using the experimental policy mechanism in all active release lines: 16.x, 18.x and, 20.x. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js.

`fs.mkdtemp()` and `fs.mkdtempSync()` can be used to bypass the permission model check using a path traversal attack

CVE-2023-32003 5.3 - Medium - August 15, 2023

`fs.mkdtemp()` and `fs.mkdtempSync()` can be used to bypass the permission model check using a path traversal attack. This flaw arises from a missing check in the fs.mkdtemp() API and the impact is a malicious actor could create an arbitrary directory. This vulnerability affects all users using the experimental permission model in Node.js 20. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Directory traversal

A vulnerability has been discovered in Node.js version 20, specifically within the experimental permission model

CVE-2023-32004 8.8 - High - August 15, 2023

A vulnerability has been discovered in Node.js version 20, specifically within the experimental permission model. This flaw relates to improper handling of Buffers in file system APIs causing a traversal path to bypass when verifying file permissions. This vulnerability affects all users using the experimental permission model in Node.js 20. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Directory traversal

The use of `module.constructor.createRequire()`

CVE-2023-32006 8.8 - High - August 15, 2023

The use of `module.constructor.createRequire()` can bypass the policy mechanism and require modules outside of the policy.json definition for a given module. This vulnerability affects all users using the experimental policy mechanism in all active release lines: 16.x, 18.x, and, 20.x. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js.

A privilege escalation vulnerability exists in Node.js 20

CVE-2023-30586 7.5 - High - July 01, 2023

A privilege escalation vulnerability exists in Node.js 20 that allowed loading arbitrary OpenSSL engines when the experimental permission model is enabled, which can bypass and/or disable the permission model. The attack complexity is high. However, the crypto.setEngine() API can be used to bypass the permission model when called with a compatible OpenSSL engine. The OpenSSL engine can, for example, disable the permission model in the host process by manipulating the process's stack memory to locate the permission model Permission::enabled_ in the host process's heap memory. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

AuthZ

The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit HTTP requests

CVE-2023-30589 7.5 - High - July 01, 2023

The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS). The CR character (without LF) is sufficient to delimit HTTP header fields in the llhttp parser. According to RFC7230 section 3, only the CRLF sequence should delimit each header-field. This impacts all Node.js active versions: v16, v18, and, v20

An untrusted search path vulnerability exists in Node.js

CVE-2023-23920 4.2 - Medium - February 23, 2023

An untrusted search path vulnerability exists in Node.js. <19.6.1, <18.14.1, <16.19.1, and <14.21.3 that could allow an attacker to search and potentially load ICU data when running with elevated privileges.

Untrusted Path

A cryptographic vulnerability exists in Node.js <19.2.0, <18.14.1, <16.19.1, <14.21.3

CVE-2023-23919 7.5 - High - February 23, 2023

A cryptographic vulnerability exists in Node.js <19.2.0, <18.14.1, <16.19.1, <14.21.3 that in some cases did does not clear the OpenSSL error stack after operations that may set it. This may lead to false positive errors during subsequent cryptographic operations that happen to be on the same thread. This in turn could be used to cause a denial of service.

A privilege escalation vulnerability exists in Node.js <19.6.1, <18.14.1, <16.19.1 and <14.21.3

CVE-2023-23918 7.5 - High - February 23, 2023

A privilege escalation vulnerability exists in Node.js <19.6.1, <18.14.1, <16.19.1 and <14.21.3 that made it possible to bypass the experimental Permissions (https://nodejs.org/api/permissions.html) feature in Node.js and access non authorized modules by using process.mainModule.require(). This only affects users who had enabled the experimental permissions option with --experimental-policy.

AuthZ

Undici is an HTTP/1.1 client for Node.js

CVE-2023-23936 5.4 - Medium - February 16, 2023

Undici is an HTTP/1.1 client for Node.js. Starting with version 2.0.0 and prior to version 5.19.1, the undici library does not protect `host` HTTP header from CRLF injection vulnerabilities. This issue is patched in Undici v5.19.1. As a workaround, sanitize the `headers.host` string before passing to undici.

Injection

The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not terminated with CLRF

CVE-2022-35256 6.5 - Medium - December 05, 2022

The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling.

HTTP Request Smuggling

A weak randomness in WebCrypto keygen vulnerability exists in Node.js 18 due to a change with EntropySource() in SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc

CVE-2022-35255 9.1 - Critical - December 05, 2022

A weak randomness in WebCrypto keygen vulnerability exists in Node.js 18 due to a change with EntropySource() in SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc. There are two problems with this: 1) It does not check the return value, it assumes EntropySource() always succeeds, but it can (and sometimes will) fail. 2) The random data returned byEntropySource() may not be cryptographically strong and therefore not suitable as keying material.

PRNG

A OS Command Injection vulnerability exists in Node.js versions <14.21.1, <16.18.1, <18.12.1, <19.0.1 due to an insufficient IsAllowedHost check

CVE-2022-43548 8.1 - High - December 05, 2022

A OS Command Injection vulnerability exists in Node.js versions <14.21.1, <16.18.1, <18.12.1, <19.0.1 due to an insufficient IsAllowedHost check that can easily be bypassed because IsIPAddress does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks.The fix for this issue in https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-32212 was incomplete and this new CVE is to complete the fix.

Shell injection

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking

CVE-2022-3602 7.5 - High - November 01, 2022

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. The risk may be further mitigated based on stack layout for any given platform/compiler. Pre-announcements of CVE-2022-3602 described this issue as CRITICAL. Further analysis based on some of the mitigating factors described above have led this to be downgraded to HIGH. Users are still encouraged to upgrade to a new version as soon as possible. In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects. Fixed in OpenSSL 3.0.7 (Affected 3.0.0,3.0.1,3.0.2,3.0.3,3.0.4,3.0.5,3.0.6).

Memory Corruption

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking

CVE-2022-3786 7.5 - High - November 01, 2022

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects.

Classic Buffer Overflow

A cryptographic vulnerability exists on Node.js on linux in versions of 18.x prior to 18.40.0 which allowed a default path for openssl.cnf

CVE-2022-32222 5.3 - Medium - July 14, 2022

A cryptographic vulnerability exists on Node.js on linux in versions of 18.x prior to 18.40.0 which allowed a default path for openssl.cnf that might be accessible under some circumstances to a non-admin user instead of /etc/ssl as was the case in versions prior to the upgrade to OpenSSL 3.

DLL preloading

A OS Command Injection vulnerability exists in Node.js versions <14.20.0, <16.20.0, <18.5.0 due to an insufficient IsAllowedHost check

CVE-2022-32212 8.1 - High - July 14, 2022

A OS Command Injection vulnerability exists in Node.js versions <14.20.0, <16.20.0, <18.5.0 due to an insufficient IsAllowedHost check that can easily be bypassed because IsIPAddress does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks.

Shell injection

CVE-2022-32213 6.5 - Medium - July 14, 2022

The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly parse and validate Transfer-Encoding headers and can lead to HTTP Request Smuggling (HRS).

HTTP Request Smuggling

The llhttp parser <v14.20.1

CVE-2022-32214 6.5 - Medium - July 14, 2022

The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS).

HTTP Request Smuggling

The llhttp parser <v14.20.1

CVE-2022-32215 6.5 - Medium - July 14, 2022

The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS).

HTTP Request Smuggling

The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli

CVE-2022-0778 7.5 - High - March 15, 2022

The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has invalid explicit curve parameters. Since certificate parsing happens prior to verification of the certificate signature, any process that parses an externally supplied certificate may thus be subject to a denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients consuming server certificates - TLS servers consuming client certificates - Hosting providers taking certificates or private keys from customers - Certificate authorities parsing certification requests from subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate which makes it slightly harder to trigger the infinite loop. However any operation which requires the public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-signed certificate to trigger the loop during verification of the certificate signature. This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the 15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected 1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc).

Infinite Loop

Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 converts SANs (Subject Alternative Names) to a string format

CVE-2021-44532 5.3 - Medium - February 24, 2022

Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.

Improper Certificate Validation

Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type

CVE-2021-44531 7.4 - High - February 24, 2022

Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 was accepting URI SAN types, which PKIs are often not defined to use. Additionally, when a protocol allows URI SANs, Node.js did not match the URI correctly.Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the --security-revert command-line option.

Improper Certificate Validation

Due to the formatting logic of the "console.table()" function it was not safe to

CVE-2022-21824 8.2 - High - February 24, 2022

Due to the formatting logic of the "console.table()" function it was not safe to allow user controlled input to be passed to the "properties" parameter while simultaneously passing a plain object with at least one property as the first parameter, which could be "__proto__". The prototype pollution has very limited control, in that it only allows an empty string to be assigned to numerical keys of the object prototype.Node.js >= 12.22.9, >= 14.18.3, >= 16.13.2, and >= 17.3.1 use a null protoype for the object these properties are being assigned to.

Prototype Pollution

Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 did not handle multi-value Relative Distinguished Names correctly

CVE-2021-44533 5.3 - Medium - February 24, 2022

Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 did not handle multi-value Relative Distinguished Names correctly. Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, for example, in order to inject a Common Name that would allow bypassing the certificate subject verification.Affected versions of Node.js that do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerable.

Improper Certificate Validation

Internally libssl in OpenSSL calls X509_verify_cert() on the client side to verify a certificate supplied by a server

CVE-2021-4044 7.5 - High - December 14, 2021

Internally libssl in OpenSSL calls X509_verify_cert() on the client side to verify a certificate supplied by a server. That function may return a negative return value to indicate an internal error (for example out of memory). Such a negative return value is mishandled by OpenSSL and will cause an IO function (such as SSL_connect() or SSL_do_handshake()) to not indicate success and a subsequent call to SSL_get_error() to return the value SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be returned by OpenSSL if the application has previously called SSL_CTX_set_cert_verify_callback(). Since most applications do not do this the SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be totally unexpected and applications may not behave correctly as a result. The exact behaviour will depend on the application but it could result in crashes, infinite loops or other similar incorrect responses. This issue is made more serious in combination with a separate bug in OpenSSL 3.0 that will cause X509_verify_cert() to indicate an internal error when processing a certificate chain. This will occur where a certificate does not include the Subject Alternative Name extension but where a Certificate Authority has enforced name constraints. This issue can occur even with valid chains. By combining the two issues an attacker could induce incorrect, application dependent behaviour. Fixed in OpenSSL 3.0.1 (Affected 3.0.0).

Infinite Loop

Next.js is a React framework

CVE-2021-43803 7.5 - High - December 10, 2021

Next.js is a React framework. In versions of Next.js prior to 12.0.5 or 11.1.3, invalid or malformed URLs could lead to a server crash. In order to be affected by this issue, the deployment must use Next.js versions above 11.1.0 and below 12.0.5, Node.js above 15.0.0, and next start or a custom server. Deployments on Vercel are not affected, along with similar environments where invalid requests are filtered before reaching Next.js. Versions 12.0.5 and 11.1.3 contain patches for this issue.

Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is used to convert strings to ASCII

CVE-2021-22918 5.3 - Medium - July 12, 2021

Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is used to convert strings to ASCII. The pointer p is read and increased without checking whether it is beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information disclosures or crashes. This function can be triggered via uv_getaddrinfo().
