AVideo through commit c91b5975d contains a reflected cross-site scripting vulnerability in userLogin.php where the cancelUri parameter is echoed in an href attribute after isSafeRedirectURL checks protocol only, not HTML characters. Unauthenticated attackers can inject event handlers via relative URLs with embedded quotes to execute arbitrary JavaScript when users interact with the Cancel button.
