RHACM multicloud-operators-subscription: privilege escalation allows exfil
CVE-2026-73137 7.7 - High - August 20, 2026

A flaw was found in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM). A tenant with HelmRelease create permissions can exploit this vulnerability by manipulating the `secretRef.Namespace` field. This allows the `GetSecret()` function in the HelmRelease controller to fetch sensitive credentials from any namespace, which are then sent to an attacker-controlled Helm repository. This can lead to the exfiltration of credentials from arbitrary namespace Secrets, resulting in information disclosure.

Information Disclosure

Arbitrary k8s resource deployment via HelmRelease multicloud-operator-subscription
CVE-2026-67567 9.9 - Critical - August 20, 2026

A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a tenant, who has the ability to create HelmRelease custom resources (CRs), to bypass existing security controls. The system's HelmRelease controller processes Helm chart templates using its own elevated ServiceAccount privileges without proper validation. This enables the tenant to deploy arbitrary resources across the entire cluster, leading to a significant security compromise.

Lighthouse Namespace Injection for Unauthorized EndpointSlice/ServiceImport
CVE-2026-66788 9.9 - Critical - August 20, 2026

A flaw was found in Lighthouse. A remote attacker, by compromising a spoke cluster, can exploit a vulnerability where the destination namespace for resource injection is derived from an attacker-controlled label or annotation on the broker object. This allows the attacker to inject unauthorized EndpointSlices and ServiceImports into any namespace on peer clusters, including critical system namespaces like kube-system and openshift-*. This could lead to privilege escalation or other forms of system compromise within the cluster.

Authorization

RedHat AMK Lighthouse IP validation flaw enabling MITM
CVE-2026-66787 8.7 - High - August 20, 2026

A flaw was found in the lighthouse component of Red Hat Advanced Cluster Management for Kubernetes. This vulnerability stems from insufficient validation of advertised IP addresses within EndpointSlice objects. A compromised spoke cluster can exploit this by creating EndpointSlices with attacker-controlled IP addresses, causing other clusters' lighthouse DNS to redirect legitimate service traffic to malicious endpoints. This enables a remote attacker to conduct transparent Man-in-the-Middle (MITM) attacks on cross-cluster service communications, potentially leading to unauthorized information disclosure and data manipulation.

Insufficient Verification of Data Authenticity

Red Hat Submariner Unauthorized Network Traffic Redirection Vulnerability
CVE-2026-66785 9.9 - Critical - August 20, 2026

A flaw was found in Submariner. This vulnerability allows a malicious cluster (spoke) to redirect network traffic from other connected clusters (peer clusters) by publishing a specially crafted network endpoint. The system fails to properly validate the network subnets provided by the malicious cluster, enabling it to declare arbitrary network ranges. Consequently, all network traffic intended for these arbitrary ranges from peer clusters will be rerouted through the attacker's tunnel, potentially leading to unauthorized information disclosure or network disruption.

Improper Input Validation

Auth Cluster Index Tampering via Delta-Sync in Search-Indexer
CVE-2026-76827 6.8 - Medium - August 19, 2026

A flaw was found in search-indexer. This vulnerability allows a registered and authenticated managed cluster to tamper with or delete another cluster's indexed search data. This is possible because the delta-sync write paths in search-indexer do not properly restrict UPDATE/DELETE operations to data owned by the calling cluster. An attacker could exploit this by crafting specific user identifiers (UIDs) with a different cluster's prefix.

Protection Mechanism Failure

Unverified Remote Script in RH acm-operator-bundle Grants Build Access
CVE-2026-76139 8 - High - August 19, 2026

A flaw was found in acm-operator-bundle. The build process for this component downloads and runs a script from a remote source without verifying its authenticity or integrity. This script gains access to sensitive credentials, such as GitHub access tokens and registry passwords, used in the build environment. A remote attacker could exploit this vulnerability to inject malicious code, leading to unauthorized access to build resources and potential compromise of the resulting operator bundle.

Privilege Escalation via overpriv ClusterRole in search-v2-operator (Red Hat)
CVE-2026-70496 9.9 - Critical - August 19, 2026

A flaw was found in search-v2-operator. The operator's ClusterRole has permissions equivalent to a cluster administrator, allowing it to impersonate other entities, write Role-Based Access Control (RBAC) configurations, approve Certificate Signing Requests (CSRs), and manage ManifestWork. This grants excessive privileges beyond what is necessary for the operator's intended function, potentially leading to privilege escalation within the cluster.

Execution with Unnecessary Privileges

RedHat volsync-addon-controller: YAML Injection via OLM Subscription Annotation
CVE-2026-18874 6.2 - Medium - August 19, 2026

A flaw was found in volsync-addon-controller. This vulnerability allows an attacker to inject malicious YAML (Yet Another Markup Language) code into the OpenShift Lifecycle Manager (OLM) Subscription resource. This is due to improper escaping of annotation values when they are rendered into YAML. Successful exploitation could lead to unauthorized modification or control over OLM Subscription configurations, potentially impacting software management within the cluster. This issue primarily affects systems where the 'volsync-addon-deploy-type: olm' annotation is explicitly enabled.

Code Injection

Privilege Escalation via Unvalidated Env Setup in Red Hat Search Operator
CVE-2026-71470 9.1 - Critical - August 19, 2026

A flaw was found in the search-v2-operator. This vulnerability allows a privileged user, specifically a Custom Resource (CR) editor, to manipulate Search CR fields such as imageOverride, arguments, and environment variables without proper validation. By exploiting this, an attacker can mount arbitrary secrets into a search container's environment or replace the container image with an attacker-controlled one. This leads to privilege escalation and can result in a full cluster compromise due to the ServiceAccount's extensive impersonation permissions.

Improper Control of Dynamically-Managed Code Resources

Submariner Operator Role Escalation Enables Cluster Mesh MITM
CVE-2026-66780 9.9 - Critical - August 18, 2026

A flaw was found in the submariner-operator component. The `submariner-k8s-broker-cluster` Role, which is assigned to joined clusters, possesses excessive permissions. This allows a compromised cluster to alter network configurations, specifically by overwriting other clusters' endpoint information. Consequently, an attacker can redirect inter-cluster tunnel traffic, enabling a Man-in-the-Middle (MITM) attack across the entire cluster mesh.

Authorization

Red Hat ACMM Submariner-Operator Escalation via Unvalidated Image Path
CVE-2026-66783 8.2 - High - August 18, 2026

A flaw was found in the `submariner-operator` component of Red Hat Advanced Cluster Management for Kubernetes.

This lack of validation enables an attacker to execute arbitrary code with elevated privileges across the entire cluster, including control-plane nodes, by deploying a malicious image.

Improper Input Validation

Submariner Operator: Broker SA Token Exposure Grants Full Mesh Control
CVE-2026-66782 7.8 - High - August 18, 2026

A flaw was found in the Submariner operator. This vulnerability allows for the exposure of a long-lived broker service account (SA) bearer token within the Submariner Custom Resource (CR) specification. An attacker with access to the cluster's etcd database or through `kubectl get` commands could obtain this token. The possession of this token grants full control over the mesh network, enabling unauthorized management of network resources such as endpoints and secrets.

Cleartext Storage of Sensitive Information

Submariner Operator Exposes Unencrypted IPsec PSK
CVE-2026-66781 6.5 - Medium - August 18, 2026

A flaw was found in the Submariner operator. The Submariner Custom Resource (CR), used for configuring network connectivity, stores the IPsec pre-shared key (PSK) in an unencrypted format. This key, which is critical for securing communication between Kubernetes clusters, can be accessed by unauthorized parties. Such access enables an attacker to passively decrypt network traffic flowing between any two clusters in the mesh, resulting in sensitive information disclosure.

When an administrator runs must-gather, credentials and tokens are captured in cleartext in the resulting archive, potentially exposing sensitive information to anyone with access to the archive.

Cleartext Storage of Sensitive Information

CVE-2026-66793: Control Bypass in RHOAM GovernancePolicy AddOn Enables Priv Escalation
CVE-2026-66793 8.8 - High - August 18, 2026

A flaw was found in the governance-policy-addon-controller component of Red Hat Advanced Cluster Management for Kubernetes. A user with permissions to annotate the namespaced ManagedClusterAddOn resource can override the governance-policy container image. This allows an attacker to run a controlled image with cluster-admin privileges on the managed cluster, leading to arbitrary code execution and privilege escalation.

Improper Input Validation

acm-search-v2-rhel9 RHEL9 RCE via WORK_MEM injection
CVE-2026-71472 9.1 - Critical - August 17, 2026

A flaw was found in acm-search-v2-rhel9. This vulnerability allows an authenticated attacker, such as a hub administrator or a Search Custom Resource (CR) editor, to inject malicious shell commands or SQL statements. This occurs because the WORK_MEM string provided in the Search CR is not properly validated before being used in a bash script and an SQL query. Successful exploitation could lead to arbitrary code execution within the privileged postgres pod, potentially compromising the system.

Shell injection

CVE-2026-70495: Overly Broad Permissions in Red Hat Search V2 Operator ServiceAccount
CVE-2026-70495 8.8 - High - August 17, 2026

A flaw was found in search-v2-operator. This component's `search-serviceaccount` has overly broad permissions, allowing it to impersonate users and groups across the entire cluster. If an attacker gains access to any of the pods running under this service account, they could exploit this to achieve `system:masters` access, granting them full control over the cluster.

Improper Privilege Management

Red Hat Multi-Cloud Operators Subscription PrivEsc via Crafted Annotations
CVE-2026-66792 9.9 - Critical - August 17, 2026

A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a user on a managed cluster to escalate their privileges by creating a Subscription with specific, crafted annotations. Successful exploitation grants the attacker the ability to deploy resources into any namespace with the elevated permissions of the controller's Service Account, potentially leading to unauthorized access and control over cluster resources.

AuthZ

CR Priv Escalation in Red Hat Insights-Client Enables Cluster-Wide Secret Read
CVE-2026-71846 6.5 - Medium - August 12, 2026

A flaw was found in insights-client. The component's ServiceAccount is bound to a ClusterRole granting cluster-wide secrets get, list, and watch permissions, while the code only requires access to a single specific Secret. This excessive privilege means that a compromise of the insights-client pod or ServiceAccount token would grant an attacker read access to all Secrets across the hub cluster, including managed-cluster kubeconfigs and other sensitive credentials.

Execution with Unnecessary Privileges

Red Hat search-v2-api Unauthenticated Cache DoS via Unbounded tokenReviews
CVE-2026-71469 7.5 - High - August 12, 2026

A flaw was found in search-v2-api. An unauthenticated attacker can exploit this by sending requests with unique random bearer tokens. Each unique token creates a permanent entry in the unbounded tokenReviews cache, which is not properly cleared. This can lead to memory exhaustion of the search-api pod, resulting in a Denial of Service (DoS).

Allocation of Resources Without Limits or Throttling

RCE via Collector.ImageOverride in acm-search-v2 (Red Hat)
CVE-2026-71471 9 - Critical - August 12, 2026

A flaw was found in acm-search-v2-rhel9. An attacker with administrative privileges on the hub cluster, specifically with patch access to the Search Custom Resource (CR), could exploit a vulnerability in the `Collector.ImageOverride` field. This allows the attacker to deploy an arbitrary container image across all managed clusters. The consequence is remote code execution (RCE), enabling the attacker to execute commands and potentially access sensitive information across the entire fleet of managed clusters.

Inclusion of Functionality from Untrusted Control Sphere

Red Hat Search-v2-Operator: Arbitrary Config Injection & Container Image Replacement
CVE-2026-71473 8.5 - High - August 12, 2026

A flaw was found in the `search-v2-operator` component. A user with specific administrative permissions on a managed cluster can exploit a vulnerability that allows them to inject arbitrary configuration data.

Confused Deputy

Red Hat OpenShift GitOps multicloud-integrations: OCM Annotation Validation Flaw
CVE-2026-72526 9.9 - Critical - August 12, 2026

A flaw was found in the multicloud-integrations component. The Application propagation controller processes the `ocm-managed-cluster` annotation from an Application Custom Resource (CR) without proper validation. A tenant with permissions to create Applications on the hub cluster can exploit this to target arbitrary managed clusters. This can force ArgoCD on the spoke clusters to synchronize attacker-controlled manifests, leading to arbitrary code execution or privilege escalation on those clusters.

Confused Deputy

Insights-client Exposes Pull-Secret via Pod Log Leakage
CVE-2026-71474 6.3 - Medium - August 11, 2026

A flaw was found in insights-client. When the application receives a non-200 response, it logs the request headers, which can include the cloud.openshift.com pull-secret token. A local user with access to pod logs on the hub could read this long-lived credential. This information disclosure could grant unauthorized access to Red Hat cloud services.

Insertion of Sensitive Information into Log File

RedHat ACM Search API RHEL9: Improper Bearer Token Reuse in Federation Cache
CVE-2026-71468 5.3 - Medium - August 11, 2026

A flaw was found in acm-search-v2-api-rhel9. When the `getFederationConfig` function refreshes its cache, it improperly reuses a user's bearer token for all subsequent federated requests until the cache expires. This allows other authenticated users to gain unauthorized access to remote managed hub search results, leading to information disclosure.

Incorrect Privilege Assignment

RedHat Insights Client URL Path Injection via Unencoded ClusterID
CVE-2026-71475 5 - Medium - August 11, 2026

A flaw was found in insights-client. A compromised managed cluster, referred to as a 'spoke', can inject unencoded data into the Insights API URL path. This occurs because the ClusterID, which is controlled by the spoke, is used directly in the request path without proper validation or URL encoding. This vulnerability allows a malicious spoke to redirect authenticated requests to unintended API endpoints, potentially leading to information disclosure or unauthorized access.

Directory traversal

insights-client logs CCX_TOKEN to pod logs (CVE-2026-71845)
CVE-2026-71845 6.3 - Medium - August 11, 2026

A flaw was found in insights-client. The setDefault() function logs the value of every environment variable it processes, including CCX_TOKEN, a bearer credential used in disconnected cluster deployments. When glog verbosity is set to level 2 or higher, the token is written in clear text to the pod log on every startup. An attacker with access to pod logs or centralized logging could obtain the credential, leading to unauthorized access to the CCX API.

Insertion of Sensitive Information into Log File

Red Hat Search-v2-API Auth Bypass via WebSocket Upgrade header
CVE-2026-71467 7.5 - High - August 11, 2026

A flaw was found in search-v2-api. The authentication middleware in the affected component unconditionally skips authentication when a request includes an `Upgrade: websocket` header. An unauthenticated attacker can exploit this by sending a specially crafted HTTP POST request to the `/federated` endpoint with the `Upgrade: websocket` header. This allows the attacker to bypass authentication and access federated search results across all configured remote managed hubs, leading to information disclosure.

ACM app-subscription controller allows cluster-admin escalation via Helm charts
CVE-2026-10090 9 - Critical - August 05, 2026

A flaw was found in the Application Subscription controller (multicluster-operators-subscription) of Red Hat Advanced Cluster Management for Kubernetes (ACM). A user with namespace-scoped "edit" privileges in an ACM hub namespace can create a Channel resource pointing to a Helm repository they control and a Subscription resource referencing it. The app-subscription controller fetches and applies the Helm chart contents with its own elevated authority, without verifying whether the subscription creator holds the "open-cluster-management:subscription-admin" role and without restricting applied resources to the subscription namespace. This allows the attacker to include cluster-scoped resources in the Helm chart, such as a ClusterRoleBinding granting the attacker's ServiceAccount the "cluster-admin" ClusterRole. Successful exploitation results in full cluster-admin privilege escalation. This contradicts the ACM documentation which states that non-subscription-admin users should have resources deployed into the subscription namespace only.

Privilege Defined With Unsafe Actions

Konnectivity Proxy-Server: Unauthenticated Agent via Missing CA Cert
CVE-2026-16242 9.4 - Critical - July 20, 2026

A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert (and without token-based agent authentication), so client certificates were not validated. A remote attacker who can reach the Konnectivity cluster endpoint could connect as an unauthenticated agent, join the routing pool, and potentially proxy, inspect, modify, or drop control-plane-to-node traffic.

Missing Authentication for Critical Function

fast-uri <=3.1.2/4.0.0 Unicode IDN Canonicalization Bug
CVE-2026-13676 7.5 - High - June 29, 2026

fast-uri versions 2.3.1 through 3.1.2 and 4.0.0 fail to canonicalize Unicode (IDN) hostnames for HTTP-family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize() and equal() still return values that differ from a WHATWG-compatible URL parser. Applications that use fast-uri to enforce host-based policy (denylists, loopback filtering, redirect validation, outbound proxy routing) before passing the same URL to Node's URL or fetch can be bypassed when the two implementations resolve the same input to different hosts. Patches: upgrade to fast-uri 3.1.3 for the 3.x line or 4.0.1 for the 4.x line. Workarounds: enforce host policy using the same URL parser used for the actual request, or reject non-ASCII hosts before policy checks.

Interpretation Conflict

Rclone 1.46.0-1.74.3: Unauthenticated GET/HEAD RCE via rcd
CVE-2026-49980 8.1 - High - June 24, 2026

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.46.0 until 1.74.3, rclone rcd --rc-serve accepts unauthenticated GET and HEAD requests to paths of the form: /[remote:path]/object. The remote value is parsed from the URL and passed to normal backend initialization. Inline remote configuration can set backend options that execute local commands during initialization. As a result, a single unauthenticated GET or HEAD request can execute a command as the rclone process user. This vulnerability is fixed in 1.74.3.

Missing Authentication for Critical Function

sanitize-html XSS via xmp in < 2.17.4 (ApostropheCMS JS CMS)
CVE-2026-44990 8.1 - High - June 12, 2026

ApostropheCMS is an open-source Node.js content management system, and sanitize-html provides a simple HTML sanitizer with a clear API. Under the default configuration, versions of `sanitize-html` prior to 2.17.4 can turn attacker-controlled content inside a disallowed `xmp` element into live HTML or JavaScript. This is a sanitizer bypass in the default `disallowedTagsMode: 'discard'` path and can lead to stored XSS in applications that render sanitized output back to users. Version 2.17.4 patches the issue.

XSS

CRLF Injection in form-data <=4.0.5 via unsanitized field names and filenames
CVE-2026-12143 7.5 - High - June 12, 2026

form-data is a library for creating readable multipart/form-data streams. In versions through 4.0.5, the `field` argument to `FormData#append` and the `filename` option are concatenated verbatim into the `Content-Disposition` header without escaping carriage return (CR), line feed (LF), or double-quote (") characters. An application that passes attacker-controlled data as a field name or filename (for example, an API gateway that turns JSON object keys into multipart field names) allows the attacker to terminate the header line and inject additional headers, or to smuggle entire additional multipart parts, into the request the application forwards to a backend. This can let the attacker add or override form fields (e.g. set `is_admin=true`) seen by the downstream parser. This is an instance of CWE-93 (CRLF injection). The fix escapes CR, LF, and `"` as `%0D`, `%0A`, and `%22` in field names and filenames, matching the serialization browsers use per the WHATWG HTML multipart/form-data encoding algorithm. Exploitation requires the consuming application to use untrusted input as a field name or filename; applications that use only fixed/trusted field names are not affected. Fixed in 2.5.6, 3.0.5, and 4.0.6.

CRLF Injection

Axios Node.js HTTP Adapter Proxy-Auth Header Leak 0.31.0/1.15.0
CVE-2026-44486 7.5 - High - June 11, 2026

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios Node.js HTTP adapter can leak proxy credentials to a redirect target in affected versions. When a request is sent through an authenticated proxy, Axios may add a Proxy-Authorization header. If Axios then follows a redirect and the redirected request is no longer sent through that proxy, the stale Proxy-Authorization header can remain on the redirected request and be sent to the redirect target. This affects Node.js's use of Axios with automatic redirects enabled and an authenticated proxy configuration. Browser adapters are not affected. This vulnerability is fixed in 0.32.0 and 1.16.0.

Information Disclosure

Axios HTTP Proxy-Authorization Header Leak via Redirection v0.32.0/1.16.0
CVE-2026-44487 7.5 - High - June 11, 2026

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axioss Node.js HTTP adapter may forward a Proxy-Authorization header to a redirected origin during specific proxy-to-direct redirect flows. This affects Node.js usage, where an initial HTTP request is sent through an authenticated HTTP proxy, redirects are followed, and the redirected URL is no longer proxied. Under affected redirect shapes, the final origin can receive the proxy credential that was intended only for the outbound proxy. This vulnerability is fixed in 0.32.0 and 1.16.0.

Insertion of Sensitive Information Into Sent Data

Axios size limit bypass in fetch adapter 1.7.0-1.15.x
CVE-2026-44488 7.5 - High - June 11, 2026

Axios is a promise based HTTP client for the browser and Node.js. Axios versions 1.7.0 through 1.15.x did not enforce configured request and response size limits when requests were sent with the fetch adapter. Applications that selected adapter: 'fetch', or ran in environments where axios resolved to the fetch adapter, could receive or send bodies larger than maxContentLength or maxBodyLength despite those limits being explicitly configured. This can cause resource exhaustion in server-side usage when a malicious or compromised server returns an oversized response, when an attacker can supply a large data: URL, or when an application forwards attacker-controlled request bodies through axios while relying on maxBodyLength as a boundary. This vulnerability is fixed in 0.32.0 and 1.16.0.

Allocation of Resources Without Limits or Throttling

Regex DoS in Axios 0.x/1.x via XSRF Cookie Name in Browser
CVE-2026-44496 7.5 - High - June 11, 2026

Axios is a promise based HTTP client for the browser and Node.js. Axios versions before 0.32.0 on the 0.x line and before 1.16.0 on the 1.x line build a regular expression from the configured XSRF cookie name without escaping regex metacharacters. In standard browser environments, an attacker who can influence the cookie name passed to axios can cause expensive regex backtracking while axios reads document.cookie. The practical impact is client-side availability degradation, such as freezing the affected browser tab while axios prepares a request. The issue does not affect ordinary Node.js HTTP adapter usage, React Native, or web workers, where axios does not read document.cookie. This vulnerability is fixed in 0.32.0 and 1.16.0.

Resource Exhaustion

Prototype Pollution in Axios 0.19.00.31.1 & 1.15.2
CVE-2026-44495 7 - High - June 11, 2026

Axios is a promise based HTTP client for the browser and Node.js. From 0.19.0 to before 0.31.1 and 1.15.2, Axios contains prototype-pollution gadgets in request config processing. If another vulnerability in the same JavaScript process has already polluted Object.prototype.transformResponse, affected Axios versions may treat that inherited value as request configuration or as an option validator. Axios does not itself create the prototype pollution. Exploitability requires a separate prototype-pollution vulnerability or equivalent attacker control over Object.prototype before Axios creates a request. This vulnerability is fixed in 0.31.1 and 1.15.2.

Code Injection

Axios Prototype Pollution MITM via proxy config, fixed in 1.16.0
CVE-2026-44494 8.7 - High - June 11, 2026

Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.16.0, the Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution in the application's dependency tree to be escalated into a full Man-in-the-Middle (MITM) attack intercepting, reading, and modifying all HTTP traffic including authentication credentials. The HTTP adapter at lib/adapters/http.js:670 reads config.proxy via standard property access, which traverses the prototype chain. Because proxy is not present in Axios defaults, the merged config object has no own proxy property, making it trivially injectable via prototype pollution. Once injected, setProxy() routes all HTTP requests through the attacker's proxy server. This vulnerability is fixed in 1.16.0.

Axios 0.32/1.16: IPv4mapped IPv6 NO_PROXY bypass issue
CVE-2026-44492 8.6 - High - June 11, 2026

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios does not normalise IPv4-mapped IPv6 addresses. When NO_PROXY lists an IPv4 address such as 127.0.0.1 or 169.254.169.254, a request URL using the IPv4-mapped IPv6 form (::ffff:7f00:1, ::ffff:a9fe:a9fe) still routes through the configured proxy. Node.js resolves these addresses to the underlying IPv4 host, so the request reaches the internal service via the proxy rather than being blocked. This vulnerability is fixed in 0.32.0 and 1.16.0.

OpenSSL PKCS#7 UAF via PKCS7_verify(); FIPS 3.6+ safe
CVE-2026-45447 8.1 - High - June 09, 2026

Issue summary: A specially crafted PKCS#7 or S/MIME signed message could trigger a use-after-free during PKCS#7 signature verification. Impact summary: A use-after-free may result in process crashes, heap corruption, or potentially remote code execution. When processing a PKCS#7 or S/MIME signed message, if the SignedData digestAlgorithms field is present as an empty ASN.1 SET, OpenSSL may incorrectly free a caller-owned BIO during PKCS7_verify(). A subsequent use of the BIO by the calling application results in a use-after-free condition. In the common case this occurs when the application later calls BIO_free() on the BIO originally passed to PKCS7_verify(). Depending on allocator behavior and application-specific BIO usage patterns, this may result in a crash or other memory corruption. In some application contexts this may potentially be exploitable for remote code execution. Applications that process PKCS#7 or S/MIME signed messages using OpenSSL PKCS#7 APIs may be affected. Applications using the CMS APIs for this processing are not affected. The FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this issue, as the affected code is outside the OpenSSL FIPS module boundary.
