Assigner: Wordfence

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.

Executive Summary

This vulnerability is an Authentication Bypass in the FindAll Membership plugin for WordPress (versions up to 1.0.4). It occurs because the plugin does not properly log in a user after verifying them through certain functions related to Facebook and Google user checks.
