⚠️ A sneaky manipulation of the `wordpress_logged_in_[hash]` could let attackers slip past multi-factor authentication in WP Cerber before version 8.9.3! Think of this like a restaurant that skips checking your reservation. If they accept anyone who claims to be on the list, unauthorized diners could waltz right in! An attacker could exploit this vulnerability to bypass multi-factor authentication, gaining unauthorized access to user accounts. This means that even if users think they’re secure with MFA, a crafty exploit could let someone in the back door, leading to potential data breaches and other malicious activities.
