Summary
The Shield Security: Blocks Bots, Protects Users, and Prevents Security Breaches plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `MfaEmailDisable` action in all versions up to, and including, 21.0.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to disable the global Email 2FA setting for the entire site.
