Exploitation evidence

Disclosed: evidence found.
CVE published 17 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 2.12.3.

Apply the Red Hat Advanced Cluster Management for Kubernetes 2.12.3 container image updates to remediate the identified vulnerabilities. Before applying this update, ensure that all previously released errata relevant to your system have been applied. The vendor advisory provides updated container images that fix these issues. No additional mitigation steps are specified or required beyond applying the update.

Description

Red Hat Advanced Cluster Management for Kubernetes 2.12.3 images and bug fix updates Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in. This advisory contains the container images for Red Hat Advanced Cluster Management for Kubernetes, which fix several bugs. See the following Release Notes documentation, which will be updated shortly for this release, for additional details about this release: https://docs.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.12/html/release_notes/ Security fix(es): * golang.org/x/oauth2: Unexpected memory consumption during token parsing in golang.org/x/oauth2 (CVE-2025-22868) * golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of golang.org/x/crypto/ssh (CVE-2025-22869)

Impact

The vulnerabilities fixed include a memory consumption issue that could affect token parsing, potentially leading to resource exhaustion, and a denial of service vulnerability in the SSH key exchange process. These issues could impact the stability and availability of the affected Red Hat Advanced Cluster Management for Kubernetes deployments. The vendor rates the security impact as Important (high). There are no known exploits in the wild at the time of this advisory.

Summary

This advisory for Red Hat Advanced Cluster Management for Kubernetes 2.12.3 provides updated container images that fix two security vulnerabilities: CVE-2025-22868, an unexpected memory consumption during token parsing in golang.org/x/oauth2, and CVE-2025-22869, a denial of service vulnerability in the key exchange of golang.org/x/crypto/ssh. These fixes are part of a broader set of bug fixes and improvements in the 2.12.3 release. The affected versions are >=2.12.0 and <2.12.3. The vendor rates the security impact as Important. No CVSS scores are provided in the advisory. The update requires applying this new container image version after ensuring all previous errata are applied.

CWE-1286Improper Validation of Syntactic Correctness of Input (opens in a new tab)
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-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
