Which packages are affected by CVE-2024-23900?

CVE-2024-23900 affects the following packages: org.jenkins-ci.plugins:matrix-project (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-23900?

Update org.jenkins-ci.plugins:matrix-project to 822.824.v14451b or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23900 is resolved across your whole dependency graph.

How do I detect CVE-2024-23900 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:matrix-project, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-23900 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is CVE-2024-23900 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-23900 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-23900?

CVE-2024-23900 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 53th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2024-23900 published, and has it been updated?

CVE-2024-23900 was published on January 24, 2024 and was last updated on October 24, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Jenkins Matrix Project Plugin 822.v01b_8c85d16d2 and earlier does not sanitize user-defined axis names of multi-configuration projects submitted through the config.xml REST API endpoint.

This allows attackers with Item/Configure permission to create or replace any config.xml file on the Jenkins controller file system with content not controllable by the attackers.
