YOP Poll <= 7.0.10 - Unauthenticated Origin Validation Error to Administrator Account Takeover via '/auth/wp-login-redirect' REST Route
The YOP Poll plugin for WordPress is vulnerable to Origin Validation Error in all versions up to, and including, 7.0.10. This is due to the plugin transmitting a wp_rest nonce to window.opener via postMessage() with a wildcard targetOrigin. This makes it possible for unauthenticated attackers to steal a REST nonce scoped to a logged-in Administrator and use it to change the Administrator's email address and password, resulting in full account takeover. The Administrator must open an attacker-controlled page in order to exploit this vulnerability.
