Jackson-Databind PTV Array Type Allowlist Bypass 2.10.0-2.18.8, 2.21.4, 3.1.4
CVE-2026-54513 8.1 - High - June 23, 2026

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray() allowlists any array type based only on clazz.isArray(), without validating the array's component (element) type against the configured allowlist. A PTV built with allowIfSubTypeIsArray() plus an explicit concrete-type allowlist therefore still permits EvilType[] even though EvilType is not allowlisted. When Jackson deserializes the elements and no per-element type IDs are present, it instantiates the component type directly with no further PTV check, bypassing the allowlist. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.

Apache HttpClient 5.6 Auth Bypass SCRAM-SHA-256 (CVE-2026-40542)
CVE-2026-40542 7.3 - High - April 22, 2026

Missing critical step in authentication in Apache HttpClient 5.6 allows an attacker to cause the client to accept SCRAM-SHA-256 authentication without proper mutual authentication verification. Users are recommended to upgrade to version 5.6.1, which fixes this issue.

Missing Critical Step in Authentication

Denial of Service in jackson-core 3.0.x via nested JSON parsing
CVE-2026-29062 7.5 - High - March 06, 2026

jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. From version 3.0.0 to before version 3.1.0, the UTF8DataInputJsonParser, which is used when parsing from a java.io.DataInput source, bypasses the maxNestingDepth constraint (default: 500) defined in StreamReadConstraints. A similar issue was found in ReaderBasedJsonParser. This allows a user to supply a JSON document with excessive nesting, which can cause a StackOverflowError when the structure is processed, leading to a Denial of Service (DoS). This issue has been patched in version 3.1.0.

Allocation of Resources Without Limits or Throttling

A flaw was found in pki-core, which could
CVE-2022-2393 5.7 - Medium - July 14, 2022

A flaw was found in pki-core, which could allow a user to get a certificate for another user identity when directory-based authentication is enabled. This flaw allows an authenticated attacker on the adjacent network to impersonate another user within the scope of the domain, but they would not be able to decrypt message content.

A flaw was found in pki-core
CVE-2021-20179 - March 15, 2021

A flaw was found in pki-core. An attacker who has successfully compromised a key could use this flaw to renew the corresponding certificate over and over again, as long as it is not explicitly revoked. The highest threat from this vulnerability is to data confidentiality and integrity.

AuthZ

A vulnerability was found in all pki-core 10.x.x version
CVE-2019-10180 4.8 - Medium - March 31, 2020

A vulnerability was found in all pki-core 10.x.x version, where the Token Processing Service (TPS) did not properly sanitize several parameters stored for the tokens, possibly resulting in a Stored Cross Site Scripting (XSS) vulnerability. An attacker able to modify the parameters of any token could use this flaw to trick an authenticated user into executing arbitrary JavaScript code.

XSS

A flaw was found in the all pki-core 10.x.x versions
CVE-2020-1696 5.4 - Medium - March 20, 2020

A flaw was found in the all pki-core 10.x.x versions, where Token Processing Service (TPS) where it did not properly sanitize Profile IDs, enabling a Stored Cross-Site Scripting (XSS) vulnerability when the profile ID is printed. An attacker with sufficient permissions could trick an authenticated victim into executing a specially crafted Javascript code.

XSS

An input validation error was found in Red Hat Certificate System's handling of client provided certificates before 8.1.20-1
CVE-2017-7509 - July 26, 2018

An input validation error was found in Red Hat Certificate System's handling of client provided certificates before 8.1.20-1. If the certreq field is not present in a certificate an assertion error is triggered causing a denial of service.

Improper Input Validation

Multiple cross-site scripting (XSS) vulnerabilities in Red Hat Certificate System (RHCS) before 8.1.1 and Dogtag Certificate System
CVE-2012-2662 - August 13, 2012

Multiple cross-site scripting (XSS) vulnerabilities in Red Hat Certificate System (RHCS) before 8.1.1 and Dogtag Certificate System allow remote attackers to inject arbitrary web script or HTML via unspecified parameters to the (1) System Agent or (2) End Entity pages.
