Unauthenticated reflected XSS via encrypted evideo payload

Published Aug 30, 2026 · Updated Aug 30, 2026

Reflected XSS in WWBN AVideo through commit e01e41ecc allows remote attackers to execute JavaScript via a crafted evideo link. url2Embed.json.php encrypts an attacker-supplied URL after filter_var validation, while Video::decodeEvideo and player templates print its videoLink into multiple HTML contexts without escaping. Victim interaction is required; execution can read non-HttpOnly cookies and CSRF tokens or issue same-origin requests in the victim's session.
