What is CVE-2026-85159?

The AVideo platform has a reflected cross-site scripting vulnerability located in the userLogin.php file. This issue arises from the improper handling of the 'cancelUri' parameter, which is echoed within an href attribute without adequate filtering of HTML characters. Attackers can exploit this by injecting malicious JavaScript through relative URLs containing quotes, enabling them to execute arbitrary scripts when users click on the 'Cancel' button. This flaw poses significant risks for users, as it could lead to further attacks or data breaches.
