## What is CVE-2025-1638?

CVE-2025-1638 is a critical authentication bypass vulnerability in Edge-Themes Alloggio Membership, published on 1 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-288 (Authentication Bypass Using an Alternate Path or Channel)
