WPBookit <= 1.0.2 - Insecure Direct Object Reference to Unauthenticated Privilege Escalation via Account Takeover

The WPBookit plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.0.2. This is due to the plugin not properly validating a user's identity prior to updating their details like password and email through the edit_profile_data() function. This makes it possible for unauthenticated attackers to change arbitrary user's email addresses and passwords, including administrators, and leverage that to gain access to their account.
