Ecosystems affected: Maven.

How do I fix GHSA-9fc7-rhq3-wm7x?

Update org.apache.jackrabbit:jackrabbit-webdav to 2.4.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9fc7-rhq3-wm7x is resolved across your whole dependency graph.

How do I detect GHSA-9fc7-rhq3-wm7x in my Maven dependencies?

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

How do I mitigate GHSA-9fc7-rhq3-wm7x 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 GHSA-9fc7-rhq3-wm7x actively exploited in the wild?

No public exploit code has been indexed for GHSA-9fc7-rhq3-wm7x 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.
