WWBN AVideo is an open source video platform. In versions 26.0 and prior, the AVideo endpoint objects/pluginSwitch.json.php allows administrators to enable or disable any installed plugin. The endpoint checks for an active admin session but does not validate a CSRF token. Additionally, the plugins database table is explicitly listed in ignoreTableSecurityCheck(), which means the ORM-level Referer/Origin domain validation in ObjectYPT::save() is also bypassed. Combined with SameSite=None on session cookies, an attacker can disable critical security plugins (such as LoginControl for 2FA, subscription enforcement, or access control plugins) by luring an admin to a malicious page. At time of publication, there are no publicly available patches.

## Summary

The AVideo endpoint `objects/pluginSwitch.json.php` allows administrators to enable or disable any installed plugin. The endpoint checks for an active admin session but does not validate a CSRF token. Additionally, the `plugins` database table is explicitly listed in `ignoreTableSecurityCheck()`, which means the ORM-level Referer/Origin domain validation in `ObjectYPT::save()` is also bypassed. Combined with `SameSite=None` on session cookies, an attacker can disable critical security plugins (such as LoginControl for 2FA, subscription enforcement, or access control plugins) by luring an admin to a malicious page.

Plugin UUIDs are not secret values. They are hardcoded in the frontend JavaScript source and are consistent across installations, making it trivial for an attacker to target specific plugins.

## Details

The `objects/pluginSwitch.json.php` endpoint checks admin status but performs no CSRF validation:

```php // objects/pluginSwitch.json.php if (!User::isAdmin()) { die('{"error": "Must be admin"}'); }

$obj = new Plugin(0); $obj->loadFromUUID($_POST['uuid']); $obj->setStatus($_POST['status']); $obj->save(); ```

The `plugins` table is explicitly excluded from the ORM security check at `objects/Object.php:529`:

```php // objects/Object.php:529 public static function ignoreTableSecurityCheck() { return array( 'plugins', // ... other tables ); } ```

This means the `save()` call does not trigger the Referer/Origin domain valid…
