Exploitation evidence

Disclosed: evidence found.
CVE published 21 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.

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 2026-10-26.

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 10.2, 4.17.30 or 1.5.1-r0.

AI-suggested

Red Hat has released updated packages and container images that fix this vulnerability. For OpenShift Container Platform, upgrades can be performed using the OpenShift CLI (oc) or web console following Red Hat's documented procedures. No additional mitigation steps are indicated beyond applying the official updates.

Description

A service for building customized OS artifacts, such as VM images and OSTree commits, that uses osbuild under the hood. Besides building images for local usage, it can also upload images directly to cloud. It is compatible with composer-cli and cockpit-composer clients. Security Fix(es): * go-jose: Go JOSE's Parsing Vulnerable to Denial of Service (CVE-2025-27144) 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.

Impact

Successful exploitation of this vulnerability could lead to denial of service conditions in affected components, potentially disrupting services that rely on Go JOSE parsing. The impact is rated as moderate by Red Hat. There are no known exploits in the wild at this time.

Summary

CVE-2025-27144 is a denial of service vulnerability in the Go JOSE parsing library used within Red Hat OpenShift Container Platform and osbuild-composer components of Red Hat Enterprise Linux 10. The flaw is classified under CWE-770 (Allocation of Resources Without Limits or Throttling). Red Hat has released updated RPM packages and container images to address this issue. The advisory covers multiple affected products including OpenShift Container Platform 4.18 and various Red Hat Enterprise Linux 10 variants. The vendor advisory confirms a moderate severity rating and provides instructions for upgrading clusters using the OpenShift CLI or web console.

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.
