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. Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the deletespace template to perform a XSS, e.g. by using URL such as: > xwiki/bin/deletespace/Sandbox/?xredirect=javascript:alert(document.domain). This vulnerability exists since XWiki 3.4-milestone-1. The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1.

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 14.10.5 (LTS) or 15.1-rc-1 or later

  1. 1. Identify the current XWiki version by checking the administration interface or the version.properties file in the installation directory
  2. 2. Plan upgrade to XWiki 14.10.5 (LTS) or 15.1-rc-1 (or later stable 15.x release)
  3. 3. Create a full backup of the XWiki database and file system (including attachments and configuration files)
  4. 4. Set up a staging/test environment running the target XWiki version
  5. 5. Restore the backup to the test environment and verify all extensions, themes, and custom configurations work correctly
  6. 6. Schedule a maintenance window for production upgrade
  7. 7. Stop the XWiki application server
  8. 8. Upgrade XWiki by deploying the new version (WAR file or full distribution)
Caveat Review release notes for deprecations; minor LTS to LTS upgrades typically safe but test customizations
