CVE-2023-29506 is a medium-severity (CVSS 5.4) Cross-site Scripting (XSS) vulnerability in org.xwiki.platform:xwiki-platform-security-authentication-default. 2 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2023-29506 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
XWiki Commons are technical libraries common to several other top level XWiki projects. It was possible to inject some code using the URL of authenticated endpoints. This problem has been patched on XWiki 13.10.11, 14.4.7 and 14.10.

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-security-authentication-default. 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-security-authentication-default to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-29506 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 CVE-2023-29506 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 CVE-2023-29506. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
