CVE-2022-36094Public exploitNetwork attack vector

Stored XSS via unescaped attachment filenames

Published Sep 8, 2022 · Updated Apr 22, 2025

Stored XSS in the attachment-history view in XWiki Platform allows remote authenticated users to execute JavaScript in viewers' browsers. The viewattachrev.vm template passes the attachment filename directly to localization output and an image alt attribute without XML escaping. An account able to attach a file with a crafted name must first store the payload, and another user must open that attachment's history; the script then runs with that viewer's web-session access.
