Exploitation evidence

Disclosed: evidence found.
CVE published 20 May 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 4.18.14 or 4.15.57.

AI-suggested

Red Hat has released fixed container images and RPM packages in OpenShift Container Platform versions 4.18.14 and 4.15.57 that address these vulnerabilities. Users running affected versions (>=4.18.0 <4.18.14 and versions prior to 4.15.57) should upgrade to these fixed releases as soon as possible. Upgrades can be performed using the OpenShift CLI (oc) or the web console. Detailed upgrade instructions are available in the official Red Hat documentation. No additional mitigations are specified by the vendor beyond applying these updates.

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 4.18.14. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHBA-2025:7865 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/4.18/html/release_notes/ Security Fix(es): * golang.org/x/oauth2/jws: Unexpected memory consumption during token parsing in golang.org/x/oauth2/jws (CVE-2025-22868) * openshift-console: OpenShift Console: Server-Side Request Forgery (CVE-2024-6538) 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/4.18/html-single/updating_clusters/index#updating-cluster-cli.

Impact

The Server-Side Request Forgery vulnerability (CVE-2024-6538) in the OpenShift Console could allow an attacker to induce the server to make HTTP requests to unintended locations, potentially leading to unauthorized access or information disclosure. The unexpected memory consumption vulnerability (CVE-2025-22868) in the golang.org/x/oauth2/jws package could lead to resource exhaustion during token parsing, potentially causing denial of service conditions. Both vulnerabilities affect on-premise or private cloud deployments of Red Hat OpenShift Container Platform. No active exploitation has been reported.

Summary

This advisory covers security updates for Red Hat OpenShift Container Platform, specifically addressing CVE-2024-6538, a Server-Side Request Forgery vulnerability in the OpenShift Console, and CVE-2025-22868, an unexpected memory consumption issue during token parsing in golang.org/x/oauth2/jws. The vulnerabilities affect OpenShift Container Platform versions 4.18.0 through 4.18.13 and 4.15 through 4.15.56. Red Hat has released fixed container images and RPM packages in versions 4.18.14 and 4.15.57 respectively. The advisory includes instructions for upgrading clusters using the OpenShift CLI or web console. The vulnerabilities have been assigned high and important security impact ratings by Red Hat Product Security. No known exploits in the wild have been reported at the time of the advisory.

Base weakness
The product receives input that is expected to be well-formed - i.e., to comply with a certain syntax - but it does not validate or incorrectly validates that the input complies with the syntax.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.

CWE-1321Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') (opens in a new tab)
Variant weakness
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
Implementation
By freezing the object prototype first (for example, Object.freeze(Object.prototype)), modification of the prototype becomes impossible.
Architecture and Design
By blocking modifications of attributes that resolve to object prototype, such as proto or prototype, this weakness can be mitigated.
Implementation · Input Validation
When handling untrusted objects, validating using a schema can be used.
