CVE-2026-34739 Details
Description
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.
A reflected cross-site scripting vulnerability has been identified in the User Location plugin for WWBN AVideo, affecting versions through 26.0. The issue arises in the testIP.php page, where the ip request parameter is echoed into an HTML input element without proper output encoding. This flaw allows an attacker to inject arbitrary HTML and JavaScript. Although the page is accessible only to admin users, the application's SameSite=None cookie policy enables cross-origin exploitation. Consequently, an attacker can trick an admin into clicking a malicious link that executes JavaScript in their authenticated session.
It is recommended to apply htmlspecialchars() when outputting the ip variable in the testIP.php file to properly encode the input and prevent script injection.
