Vulnerability Overview

The Really Simple Security (Free, Pro, and Pro Multisite) plugins for WordPress are vulnerable to authentication bypass in versions 9.0.0 to 9.1.1.1. This is due to improper user check error handling in the two-factor REST API actions with the 'check_login_and_get_user' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, when the "Two-Factor Authentication" setting is enabled (disabled by default).

Technical Analysis

REMEDIATION: Update to version 9.1.2, or a newer patched version --- IDENTIFIER: CWE-288 (Authentication Bypass Using an Alternate Path or Channel) The product requires authentication, but the product has an alternate path or channel that does not require authentication.
