CVE-2022-23622Network attack vector

Browser script execution via unescaped redirect field

Published Feb 9, 2022 · Updated Apr 23, 2025

Cross-site scripting in XWiki Platform allows remote attackers to run script in a user's browser through a crafted registration URL. The registerinline.vm template writes the xredirect request value into a hidden input without XML escaping, allowing injected markup to reach the response. Exploitation requires open registration, guest users blocked from viewing the registration page, and a user who follows the crafted URL; script executes in that user's XWiki origin.
