Reflected XSS via unchecked authentication wiki reference

Published Apr 16, 2023 · Updated Feb 6, 2025

Reflected XSS in affected XWiki Platform releases allows remote attackers to run script in a user's browser via a crafted authentication URL. AuthenticationResourceReferenceHandler accepted a URL-derived wiki reference without confirming that the wiki existed, allowing attacker-controlled text to reach an HTML authentication template. No account is required, but a user must open the crafted reset-password or forgot-username URL; resulting script runs with that user's XWiki origin privileges.
