Which packages are affected by GHSA-324h-2v7h-q3xx?

GHSA-324h-2v7h-q3xx affects the following packages: org.jenkins-ci.plugins:yaml-axis (Maven). Ecosystems affected: Maven.

How do I fix GHSA-324h-2v7h-q3xx?

Update org.jenkins-ci.plugins:yaml-axis to 0.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-324h-2v7h-q3xx is resolved across your whole dependency graph.

How do I detect GHSA-324h-2v7h-q3xx in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:yaml-axis. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-324h-2v7h-q3xx 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.

How does O3 Security protect against GHSA-324h-2v7h-q3xx?

O3 pinpoints whether GHSA-324h-2v7h-q3xx is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-324h-2v7h-q3xx actively exploited in the wild?

No public exploit code has been indexed for GHSA-324h-2v7h-q3xx 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 GHSA-324h-2v7h-q3xx?

GHSA-324h-2v7h-q3xx has an EPSS (Exploit Prediction Scoring System) score of 2.9%, placing it in the 85th 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.

What type of vulnerability is GHSA-324h-2v7h-q3xx?

GHSA-324h-2v7h-q3xx is classified as Deserialization of Untrusted Data (CWE-502). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-324h-2v7h-q3xx published, and has it been updated?

GHSA-324h-2v7h-q3xx was published on May 24, 2022 and was last updated on February 16, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Yaml Axis Plugin 0.2.0 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to configure a multi-configuration (Matrix) job, or control the contents of a previously configured job’s SCM repository.

Yaml Axis Plugin 0.2.1 configures its YAML parser to only instantiate safe types.
