Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
XWiki Platform is a generic wiki platform. Starting in version 3.0-milestone-1, it's possible to execute a script with the right of another user, provided the target user does not have programming right. The problem has been patched in XWiki 14.8-rc-1, 14.4.5, and 13.10.10. There are no known workarounds for this issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-863

An authorization check exists but is flawed, so it passes when it should fail. Attackers probe roles and object references to find the gap. Remediation means centralising and correctly implementing the access-control logic, then testing it against every role.

Recommended fix High confidence

XWiki 13.10.10 (for 13.x users), 14.4.5 (for 14.0-14.4 users), or 14.8+ (for 14.5+ users)

  1. 1. Identify your current XWiki version by checking the administration interface or running 'grep version' in your pom.xml/build configuration
  2. 2. If running 13.x version (>=3.1, <13.10.10), upgrade to XWiki 13.10.10 or later in the 13.x line
  3. 3. If running 14.0-14.4.x version (>=14.0, <14.4.5), upgrade to XWiki 14.4.5 or later in the 14.4.x line
  4. 4. If running 14.5-14.7.x version (>=14.5, <14.8), upgrade to XWiki 14.8 or later
  5. 5. If running version 3.0, upgrade to the latest supported version (14.10 or later recommended)
  6. 6. After upgrade, verify the patch is applied by checking the commit 4b75f212c2dd2dfc5fb5726c7830c6dbc9a425c6 is included
  7. 7. Test that script execution with another user's rights now properly enforces authorization checks
  8. 8. Review user permissions to ensure only trusted users have programming rights
Caveat Minor - this is a security fix; major version upgrades may introduce breaking changes, review release notes for your target version
