Official description

WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains an open redirect vulnerability in the login flow where a user-supplied redirectUri parameter is reflected directly into a JavaScript `document.location` assignment without JavaScript-safe encoding. After a user completes the login popup flow, a timer callback executes the redirect using the unvalidated value, sending the victim to an attacker-controlled site. Version 26.0 fixes the issue.
