Technical Description
The WP 2FA – Two-factor authentication for WordPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.5.0. This is due to missing or incorrect nonce validation on the send_backup_codes_email function. This makes it possible for unauthenticated attackers to send emails with arbitrary content to registered users via a forged request granted they can trick a site administrator or other registered user into performing an action such as clicking on a link. While a nonce check is present, it is only executed if a nonce is set. By omitting a nonce from the request, the check can be bypassed.
Remediation
Check the references section for vendor advisories and patches from melapress. Update wp_2fa to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
