Exploitation evidence

Disclosed: evidence found.
CVE published 1 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 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 or the CVSS exploit maturity 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 1.2.2.

AI-suggested

Red Hat has released version 1.2.2 of the multicluster global hub container images which include fixes for these vulnerabilities. Users should update to version 1.2.2 or later to remediate these issues. Prior to applying this update, ensure all previously released errata have been applied. No additional mitigation steps are indicated by the vendor advisory.

Description

Red Hat multicluster global hub 1.2.2 images This advisory contains the container images for multicluster global hub. These container images provide enhancements. Security Fix(es) from Bugzilla: * golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of golang.org/x/crypto/ssh (CVE-2025-22869) * golang.org/x/oauth2/jws: Unexpected memory consumption during token parsing in golang.org/x/oauth2/jws (CVE-2025-22868) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Impact

Successful exploitation of CVE-2025-22869 could cause denial of service in the SSH key exchange process, potentially disrupting service availability. CVE-2025-22868 could lead to unexpected memory consumption during token parsing, which may degrade system performance or cause resource exhaustion. Red Hat rates the overall security impact of these fixes as Important, indicating a high but not critical severity level.

Summary

This advisory addresses two security vulnerabilities in Red Hat multicluster global hub prior to version 1.2.2. The first vulnerability (CVE-2025-22869) is a denial of service issue in the key exchange mechanism of the golang.org/x/crypto/ssh package. The second vulnerability (CVE-2025-22868) involves unexpected memory consumption during token parsing in the golang.org/x/oauth2/jws package. Both vulnerabilities stem from third-party Go libraries used within the product. Red Hat has released updated container images in version 1.2.2 that include fixes for these issues.

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.
