# Grav Login plugin: two-factor check skipped, giving admin accounts access

Link for people: https://infrastack.ai/live/CVE-2026-126294 (this .md is for agents)

The Grav Login plugin before 3.11.0 lets someone who knows an account password skip two-factor verification when the global twofa_enabled setting is off. The attacker gets a session with full account permissions, including super-admin control.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Login plugin version in the Grav admin plugins list or `plugins/login/blueprints.yaml` against the fixed version.
- Check whether `twofa_enabled` is set to off in the Login plugin configuration.
- Check whether the API plugin is installed, since the sources say it accepts the resulting session.

## Fix

- Grav Login plugin: move to `3.11.0` or later.

## From the sources

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.
