AI-suggested

Upgrade the Defender Security WordPress plugin to version 6.4.1 or later, where this issue is fixed. No other mitigation is indicated as the fix is available in the updated version.

Description

The Defender Security WordPress plugin versions before 6.4.1 do not limit the number of failed two-factor authentication attempts by default. This allows an attacker who already knows a user's password to brute-force the one-time authentication code, potentially bypassing the second factor of authentication.
