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.

CVE-2023-29208 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (13.10.11, 14.4.7, 14.10); upgrading removes the vulnerable code path.

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.

1. What is CVE-2023-29208? CVE-2023-29208 is a high-severity security vulnerability in org.xwiki.platform:xwiki-platform-oldcore (maven), affecting versions >= 1.2-milestone-1, < 13.10.11. It is fixed in 13.10.11, 14.4.7, 14.10.
2. How severe is CVE-2023-29208? CVE-2023-29208 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of org.xwiki.platform:xwiki-platform-oldcore are affected by CVE-2023-29208? org.xwiki.platform:xwiki-platform-oldcore (maven) versions >= 1.2-milestone-1, < 13.10.11 is affected.
4. Is there a fix for CVE-2023-29208? Yes. CVE-2023-29208 is fixed in 13.10.11, 14.4.7, 14.10. Upgrade to this version or later.
5. Is CVE-2023-29208 exploitable, and should I be worried? Whether CVE-2023-29208 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2023-29208 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2023-29208?
   • Upgrade org.xwiki.platform:xwiki-platform-oldcore to 13.10.11 or later
   • Upgrade org.xwiki.platform:xwiki-platform-oldcore to 14.4.7 or later
   • Upgrade org.xwiki.platform:xwiki-platform-oldcore to 14.10 or later
