CVE-2023-29208 is a high-severity (CVSS 7.5) CWE-668 vulnerability in org.xwiki.platform:xwiki-platform-oldcore. 2 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2023-29208 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. Rights added to a document are not taken into account for viewing it once it's deleted. Note that this vulnerability only impact deleted documents that where containing view rights: the view rights provided on a space of a deleted document are properly checked. The problem has been patched in XWiki 14.10 by checking the rights of current user: only admin and deleter of the document are allowed to view it.

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-oldcore. 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-oldcore to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-29208 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-2023-29208 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-2023-29208. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
