Original source text (not a translation)

Grav Login Plugin versions before 3.8.13 contain an insufficient session expiration vulnerability in TokenStorage.php where the findTriplet() method fails to properly validate Remember Me token timestamps. Attackers with a captured Remember Me cookie can authenticate indefinitely instead of the configured timeout period, as the expiry check compares an array to a scalar value which always evaluates incorrectly in PHP.
