Which packages are affected by GHSA-rqgj-rqfr-5j6f?

GHSA-rqgj-rqfr-5j6f affects the following packages: mantisbt/mantisbt (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-rqgj-rqfr-5j6f?

Update mantisbt/mantisbt to 2.25.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rqgj-rqfr-5j6f is resolved across your whole dependency graph.

How do I detect GHSA-rqgj-rqfr-5j6f in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mantisbt/mantisbt, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-rqgj-rqfr-5j6f 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-rqgj-rqfr-5j6f actively exploited in the wild?

No public exploit code has been indexed for GHSA-rqgj-rqfr-5j6f 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-rqgj-rqfr-5j6f?

GHSA-rqgj-rqfr-5j6f has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 56th 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.
