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 ORMs domain-based security check executes. Combined with SameSite=None cookie policy, a cross-origin POST can overwrite the platforms logo with attacker-controlled content.
