CVE-2026-8457 is an authentication bypass vulnerability in the WooCommerce - Social Login plugin for WordPress affecting all versions up to and including 2.8.7. The flaw is in the plugin's Apple login handler, which accepts an Apple id_token and decodes only its base64 payload without verifying the JWT signature against Apple's public keys and without validating critical claims such as issuer, audience, and expiry. The login flow is further weakened because the nonce required to invoke it is exposed to unauthenticated users through a localized JavaScript object on the login page. By forging an id_token whose payload contains the email address of an existing WordPress user, an unauthenticated attacker can cause the plugin to resolve that account and immediately create an authenticated session for it, including for administrator accounts.
