WWBN AVideo affected by CSRF on Site Customization Endpoint Enables Logo Overwrite via Base64 File Write

WWBN AVideo is an open source video platform. In versions 26.0 and prior, the site customization endpoint at admin/customize_settings_nativeUpdate.json.php lacks CSRF token validation and writes uploaded logo files to disk before the ORM's domain-based security check executes. Combined with SameSite=None cookie policy, a cross-origin POST can overwrite the platform's logo with attacker-controlled content.
