What is CVE-2025-12628?

The WP 2FA WordPress plugin is compromised by a vulnerability that stems from insufficient randomness in the generation of backup codes. This weakness allows potential attackers to exploit the two-factor authentication mechanism by brute forcing the predictable backup codes. Consequently, this significantly undermines the protective layer of the plugin, potentially granting unauthorized access to users' accounts.
