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 offering runtime services for applications built on top of it. In versions 4.2-milestone-2 through 16.10.6, configuration files are accessible through jsx and sx endpoints. It's possible to access and read configuration files by using URLs such as `http://localhost:8080/bin/ssx/Main/WebHome?resource=../../WEB-INF/xwiki.cfg&minify=false`. This is fixed in version 16.10.7.

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.

Recommended fix High confidence

XWiki 16.10.7 or later (note: versions 17.x may require separate patching; consider 17.4.0+ if available)

  1. 1. Back up your current XWiki installation and database
  2. 2. Download XWiki version 16.10.7 or later from the official XWiki downloads page (https://www.xwiki.org/xwiki/bin/view/Download/)
  3. 3. Stop the XWiki application server
  4. 4. Replace the existing XWiki files with the new version files, preserving your configuration and data directories
  5. 5. Restart the XWiki application server
  6. 6. Verify the installation by attempting to access a known configuration file via the path traversal URL pattern (e.g., /bin/ssx/Main/WebHome?resource=../../WEB-INF/xwiki.cfg&minify=false) - this should now return a 404 or be blocked
  7. 7. Check that normal wiki functionality still works as expected
