Vulnerability Overview

The Booking Calendar and Notification plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 4.0.3. This is due to the plugin not properly verifying a user's identity prior to logging them in. This makes it possible for unauthenticated attackers to log in as other users which makes privilege escalation possible.
