Vulnerability in Edge-Themes Alloggio Membership

CVE-2025-1638

The Alloggio Membership plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.0.2. This is due to the plugin not properly validating a user's identity through the alloggio_membership_init_rest_api_facebook_login and alloggio_membership_init_rest_api_google_login functions. This makes it possible for unauthenticated attackers to log in as any user, including administrators, without knowing a password.
