Description
The Shield: Blocks Bots, Protects Users, and Prevents Security Breaches plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 21.0.9 via the MfaGoogleAuthToggle class due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to disable Google Authenticator for any user.
