Description
Impact
A registered user can perform remote code execution leading to privilege escalation by injecting the proper code in the "property" field of an attachment selector, as a gadget of their own dashboard. Note that the vulnerability does not impact comments of a wiki.
Patches
The vulnerability has been patched in XWiki 13.10.11, 14.4.8, 14.10.2, 15.0-rc-1.
Workarounds
The problem can be worked around by applying following changes directly in XWiki.AttachmentSelector page: https://github.com/xwiki/xwiki-platform/commit/5e8725b4272cd3e5be09d3ca84273be2da6869c1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-attachment-ui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.xwiki.platform:xwiki-platform-attachment-ui to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3hjg-cghv-22ww is resolved across your whole dependency graph.
Workarounds
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.
How O3 protects you
O3 pinpoints whether GHSA-3hjg-cghv-22ww is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-3hjg-cghv-22ww. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-3hjg-cghv-22ww in your dependencies?
O3 detects GHSA-3hjg-cghv-22ww across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
