Details

Grav Login plugin 2.7.0 before 3.9.9 contains an authentication bypass vulnerability that allows attackers with a valid password to skip two-factor authentication through remember-me cookie restoration. Attackers can obtain a persistent remember-me cookie after the password step and restore it as a fully authorized session without completing the second factor.
