What is CVE-2025-13539?

CVE-2025-13539 is a critical authentication bypass vulnerability in Elated Themes FindAll Membership, published on 27 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The FindAll Membership plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.0.4. This is due to the plugin not properly logging in a user with the data that was previously verified through the 'findall_membership_check_facebook_user' and the 'findall_membership_check_google_user' functions. This makes it possible for unauthenticated attackers to log in as administrative users, as long as they have an existing account on the site which can easily be created by default through the temp user functionality, and access to the administrative user's email.

Weakness: CWE-288
