CVE-2025-7066Network attack vector

Stored XSS via comma-separated MIME type

Published Jul 4, 2025 · Updated Sep 16, 2025

Stored XSS in Jirafeau before 4.6.3 allows remote attackers to execute JavaScript in a user's browser through a crafted file preview. The jirafeau_is_viewable function accepts a stored MIME type whose first slash-delimited token is an allowed media class but does not reject a comma followed by text/html, so the browser interprets the preview as HTML. A victim must open the attacker-uploaded file preview; the script then runs in the Jirafeau origin and exposes data and actions available to that browser session.
