Vulnerability from github – Published: 2026-08-02 00:31 – Updated: 2026-08-02 00:31

Details

The WooCommerce - Social Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to and including 2.8.7. This is due to the plugin's Apple login handler accepting the Apple id_token and decoding only its base64 payload without verifying the JWT signature against Apple's public keys or validating the issuer, audience, or expiry claims, combined with the security nonce required to invoke the login flow being publicly exposed to unauthenticated users via a localized JavaScript object on the login page. This makes it possible for unauthenticated attackers to log in as any existing WordPress user — including administrators — by supplying a forged id_token whose payload contains the target user's email address, as that email is used without any role exclusion to resolve a WordPress account and immediately issue an authenticated session for it.

Severity

9.8 (Critical)
