CVE-2026-109312

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.
