CVE-2026-33296Public exploitNetwork attack vector

User redirection via unencoded redirectUri assignment

Published Mar 22, 2026 · Updated Mar 22, 2026

Open redirect in World Wide Broadcast Network AVideo before 26.0 allows remote attackers to redirect users via a crafted login URL. The view/userLogin.php login flow writes redirectUri into a JavaScript document.location string without JavaScript-context encoding, so its timer navigates to an attacker URL after the popup closes. Exploitation requires a user to follow the crafted link and complete or dismiss the login popup, enabling phishing through an attacker-controlled page.
