## What is DRUPAL-CONTRIB-2023-030?

DRUPAL-CONTRIB-2023-030 is an authentication bypass vulnerability in drupal/tfa, published on 12 Jul 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This module enables you to allow and/or require users to use a second authentication method in addition to password authentication.

The module doesn't sufficiently ensure all core login routes, including the password reset page, require a second factor credential.

This vulnerability is mitigated by the fact that an attacker must obtain a first-factor login credential.

What it is: DRUPAL-CONTRIB-2023-030 is an authentication bypass vulnerability in drupal/tfa, published on 12 Jul 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2023-030 in the wild and no public exploit code.

Affected product: drupal/tfa. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
