Which packages are affected by GHSA-rrff-chj9-w4c7?

GHSA-rrff-chj9-w4c7 affects the following packages: org.apache.jspwiki:jspwiki-main (Maven), org.apache.jspwiki:jspwiki-markdown (Maven). Ecosystems affected: Maven.

How do I fix GHSA-rrff-chj9-w4c7?

Update org.apache.jspwiki:jspwiki-main to 2.12.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rrff-chj9-w4c7 is resolved across your whole dependency graph.

How do I detect GHSA-rrff-chj9-w4c7 in my Maven dependencies?

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

How do I mitigate GHSA-rrff-chj9-w4c7 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-rrff-chj9-w4c7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-rrff-chj9-w4c7 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-rrff-chj9-w4c7?

GHSA-rrff-chj9-w4c7 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 42th 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-rrff-chj9-w4c7?
