Description
Grav Login Plugin adds login, basic ACL, and session wide messages to Grav. Prior to 3.8.11, the Grav Login plugin login.regenerate2FASecret task checks only that the pending-session user exists rather than requiring $user->authorized. After submitting a victim-s correct password, an attacker can invoke taskRegenerate2FASecret() during the pending TOTP challenge, overwrite twofa_secret, read the replacement secret from the response, calculate a valid code, and complete authentication without the victim-s second factor. This issue is fixed in version 3.8.11.
