CVE-2026-85159 Details
Description
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.
A reflected cross-site scripting vulnerability has been identified in AVideo versions through commit c91b5975d. The issue resides in userLogin.php, where the cancelUri parameter is echoed into an href attribute. The isSafeRedirectURL function only verifies the protocol and domain, neglecting HTML character sanitation. This oversight allows unauthenticated attackers to inject event handlers via relative URLs containing quotes, executing arbitrary JavaScript when users hover over the Cancel button.
Apply htmlspecialchars to the cancelUri parameter before outputting it in the href attribute, in addition to the existing isSafeRedirectURL protocol check.
