Exploitation evidence

Disclosed: evidence found.
CVE published 6 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 26 Oct 2026.

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.

AI-suggested

Red Hat has released updated container images in version 2.10.8 that address these vulnerabilities. Users should apply this update after ensuring all previous errata are applied. No additional mitigation steps are indicated beyond applying the updated container images provided by Red Hat. Patch status is confirmed by the vendor advisory.

Description

Red Hat Advanced Cluster Management for Kubernetes 2.10.8 images 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/2.10/html/release_notes/ Security fix(es): * golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of golang.org/x/crypto/ssh (CVE-2025-22869) * golang-jwt/jwt: jwt-go allows excessive memory allocation during header parsing (CVE-2025-30204)

Impact

The vulnerabilities fixed in this update could lead to denial of service conditions due to resource exhaustion caused by improper handling in cryptographic key exchange and JWT header parsing. This could impact the availability and stability of the Red Hat Advanced Cluster Management for Kubernetes environment, potentially affecting administrators and site reliability engineers managing multiple clusters.

Summary

This advisory covers security fixes in Red Hat Advanced Cluster Management for Kubernetes version 2.10.8 container images. It addresses two main vulnerabilities: CVE-2025-22869, a denial of service issue in the key exchange mechanism of golang.org/x/crypto/ssh, and CVE-2025-30204, which allows excessive memory allocation during JWT header parsing in the golang-jwt/jwt library. These vulnerabilities could potentially disrupt cluster management operations by exhausting resources. The update includes container image replacements that fix these issues and other bugs.

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.

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.
