Title
Grav Login Plugin 2.7.0 before 3.9.9 2FA Bypass via Profile Update Form
Summary
Grav Login plugin 2.7.0 before 3.9.9 contains an authentication bypass in processUserProfile(), which checks that the session user exists but not that a pending front-end 2FA session is fully authorized. Attackers with a victim's password who can publish a page form without an access rule can invoke update_user before completing 2FA to disable twofa_enabled and take over the account.
