CVE-2026-85682
YOP Poll <= 7.0.10 - Unauthenticated Origin Validation Error to Administrator Account Takeover via '/auth/wp-login-redirect' REST Route

EPSS Percentile
0th
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.
