How do I fix GHSA-f963-4cq8-2gw7?

Update org.xwiki.platform:xwiki-platform-web-templates to 15.10-rc-1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f963-4cq8-2gw7 is resolved across your whole dependency graph.

How do I detect GHSA-f963-4cq8-2gw7 in my Maven dependencies?

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

How do I mitigate GHSA-f963-4cq8-2gw7 if there is no patch (or I can't update yet)?

Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.

Is GHSA-f963-4cq8-2gw7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-f963-4cq8-2gw7 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.
