How severe is GHSA-h6qc-455m-7v6v?

GHSA-h6qc-455m-7v6v has a CVSS score of 8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-h6qc-455m-7v6v?

GHSA-h6qc-455m-7v6v affects the following packages: org.jenkins-ci.plugins:matrix-project (Maven). Ecosystems affected: Maven.

How do I fix GHSA-h6qc-455m-7v6v?

Update org.jenkins-ci.plugins:matrix-project to 1.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h6qc-455m-7v6v is resolved across your whole dependency graph.

How do I detect GHSA-h6qc-455m-7v6v 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 GHSA-h6qc-455m-7v6v if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-h6qc-455m-7v6v actively exploited in the wild?

No public exploit code has been indexed for GHSA-h6qc-455m-7v6v 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-h6qc-455m-7v6v?

GHSA-h6qc-455m-7v6v has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 60th 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-h6qc-455m-7v6v?

GHSA-h6qc-455m-7v6v is classified as Cross-site Scripting (XSS) (CWE-79). 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-h6qc-455m-7v6v published, and has it been updated?

GHSA-h6qc-455m-7v6v 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.

☕org.jenkins-ci.plugins:matrix-project

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

Matrix Project Plugin 1.16 and earlier does not escape node names shown in tooltips on the overview page of builds with a single axis. This results in a stored cross-site scripting (XSS) vulnerability exploitable by users with Agent/Configure permission.

Matrix Project Plugin 1.17 escapes the node names shown in these tooltips.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
