Exploitation evidence

Disclosed: evidence found.
CVE published 23 Apr 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Red Hat to 4.16.39.

AI-suggested

Red Hat has released OpenShift Container Platform 4.16.39 containing fixes for these vulnerabilities. Users are strongly advised to upgrade to version 4.16.39 using the OpenShift CLI (oc) or web console as soon as the updated packages and images are available in their release channel. Detailed upgrade instructions are provided in Red Hat's official documentation. No alternative mitigations or workarounds are specified in the advisory.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.16.39. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHBA-2025:4010 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html/release_notes/ Security Fix(es): * golang-jwt/jwt: jwt-go allows excessive memory allocation during header parsing (CVE-2025-30204) * baremetal-operator/apis: Bare Metal Operator (BMO) can expose any secret from other namespaces via BMCEventSubscription CRD (CVE-2025-29781) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html-single/updating_clusters/index#updating-cluster-cli.

Impact

The Bare Metal Operator vulnerability (CVE-2025-29781) can lead to unauthorized exposure of secrets across namespaces, potentially compromising sensitive information. The golang-jwt/jwt vulnerability (CVE-2025-30204) could cause excessive memory allocation during JWT header parsing, which may lead to denial of service or resource exhaustion. These impacts affect on-premise or private cloud deployments of OpenShift Container Platform 4.16 prior to 4.16.39.

Summary

This advisory covers security updates in Red Hat OpenShift Container Platform 4.16.39, which fixes two notable vulnerabilities: CVE-2025-29781 in the Bare Metal Operator (BMO) that could expose secrets from other namespaces through the BMCEventSubscription Custom Resource Definition (CRD), and CVE-2025-30204 in the golang-jwt/jwt library that allows excessive memory allocation during JWT header parsing. The update addresses these issues by providing patched container images and RPM packages. The advisory recommends upgrading to version 4.16.39 to mitigate these vulnerabilities. No CVSS scores are provided in the advisory, but the severity is rated as high by Red Hat Product Security.

CWE-653Improper Isolation or Compartmentalization (opens in a new tab)
Class weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product does not properly compartmentalize or isolate functionality, processes, or resources that require different privilege levels, rights, or permissions.
Architecture and Design
Break up privileges between different modules, objects, or entities. Minimize the interfaces between modules and require strong access control between them.

CWE-405Asymmetric Resource Consumption (Amplification) (opens in a new tab)
Class weakness
The product does not properly control situations in which an adversary can cause the product to consume or produce excessive resources without requiring the adversary to invest equivalent work or otherwise prove authorization, i.e., the adversary's influence is "asymmetric."
Architecture and Design
An application must make resources available to a client commensurate with the client's access level.
Architecture and Design
An application must, at all times, keep track of allocated resources and meter their usage appropriately.
System Configuration
Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.

Use a language that provides appropriate memory abstractions.
