Lifecycle Timeline
4Description
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the User_Location plugin's testIP.php page reflects the ip request parameter directly into an HTML input element without applying htmlspecialchars() or any other output encoding. This allows an attacker to inject arbitrary HTML and JavaScript via a crafted URL. Although the page is restricted to admin users, AVideo's SameSite=None cookie configuration allows cross-origin exploitation, meaning an attacker can lure an admin to a malicious link that executes JavaScript in their authenticated session. At time of publication, there are no publicly available patches.

Affecting AVideo 26.0 and earlier, the vulnerability exploits SameSite=None cookie configuration to enable cross-origin exploitation, permitting unauthenticated attackers to lure admins to malicious links that hijack their authenticated context. …
