CVE-2022-36097Public exploitNetwork attack vector

Stored script execution via unescaped attachment name

Published Sep 8, 2022 · Updated Apr 22, 2025

Cross-site scripting in XWiki Platform 14.0-rc-1 and later, before 14.4-rc-1, allows remote authenticated users to run script in a victim's browser. The moveStep1.vm template passes the attachment name into attachment.move.title without XML escaping, so markup in the stored filename reaches the rendered heading. An attacker needs permission to upload the crafted attachment, and a victim with move rights must open its move form; the script then runs in that victim's XWiki origin.
