CVE-2026-89241Network attack vectorHinoki check available

Script execution via unencoded form action

Published Sep 11, 2026 · Updated Sep 11, 2026

Reflected XSS in WWBN AVideo allows remote attackers to execute script in a victim's browser through a crafted password-confirmation URL. confirmLivePassword.php inserts REQUEST_URI into a form action attribute without encoding, so a quote breaks the attribute and injects event handlers. Exposure applies through commit c3edcc274c389816d434acadac07ee78eaf330c1 and requires a victim to open the malicious URL; injected code runs within the site's origin.
