Grav Login plugin before 3.11.0 contains an authentication bypass vulnerability that allows attackers with an account password to skip two-factor verification when the global twofa_enabled setting is off. Attackers can sign in through the /login form, remember-me cookie, or magic link to obtain a session the API plugin accepts, gaining full account permissions including super-admin control.
