WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains an open redirect vulnerability in the login flow where a user-supplied redirectUri parameter is reflected directly into a JavaScript `document.location` assignment without JavaScript-safe encoding. After a user completes the login popup flow, a timer callback executes the redirect using the unvalidated value, sending the victim to an attacker-controlled site. Version 26.0 fixes the issue.

CVE-2026-33296 [LOW] CWE-601 AVideo has an Open Redirect via Unvalidated redirectUri in userLogin.php
AVideo has an Open Redirect via Unvalidated redirectUri in userLogin.php
### Summary
WWBN/AVideo contains an open redirect vulnerability in the login flow where a user-supplied redirectUri parameter is reflected directly into a JavaScript `document.location` assignment without JavaScript-safe encoding. After a user completes the login popup flow, a timer callback executes the redirect using the unvalidated value, sending the victim to an attacker-controlled site.
### Details
In `view/userLogin.php`, the application accepts a redirectUri GET parameter, passes it through a function called `isSafeRedirectURL()`, and stores the result in $safeRedirectUri. This value is then embedded into an inline JavaScript block:
```php
var logintimer = setInterval(function() {
if (win.closed) {
clearIn
