GHSA-F9WW-JJG2-8XJ5
Vulnerability from github – Published: 2026-09-11 12:33 – Updated: 2026-09-11 12:33WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in plugin/Live/confirmLivePassword.php. The script interpolates the unauthenticated GET parameter u (which is not covered by $securityFilter) directly into an attribute without URL- or HTML-encoding. A remote attacker can craft a link containing a double-quote character in u (with a non-empty key parameter and no valid c parameter) to close the src attribute and inject an additional tag with an onerror handler, executing arbitrary JavaScript in the site's origin in the browser of any user, including an administrator, who opens the link. No patched version was available at the time of the advisory.
