Description

The CE21 Suite plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.2.0. This is due to hardcoded encryption key in the 'ce21_authentication_phrase' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.

Affected products

ce21com CE21 Suite: before 2.2.1 — fixed in 2.2.1

How to fix

Upgrade to a fixed version: ce21com CE21 Suite 2.2.1. Check the vendor advisory for mitigations.
