> Attackers can bypass admin approval during SAML registration to create accounts, potentially gaining unauthorized access if default roles have elevated permissions.

- **Severity:** Not scored
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** Yes

## What is DRUPAL-CONTRIB-2020-006?

DRUPAL-CONTRIB-2020-006 is an authentication bypass vulnerability in drupal/saml_sp, published on 11 Mar 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This module enables you to authenticate Drupal users using an external SAML Identity Provider.

If the site is configured to allow visitors to register for user accounts but administrator approval is required, the module doesn't sufficiently enforce the administrative approval requirement, in the case where the requesting user has already authenticated through SAML.

This vulnerability is mitigated by the fact that user accounts created in this way have only default roles, which may not have access significantly beyond that of an anonymous user. To mitigate the vulnerability without upgrading sites could disable public registration.

Check this codebase for DRUPAL-CONTRIB-2020-006 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2020-006 is an authentication bypass vulnerability in drupal/saml_sp, published on 11 Mar 2020. 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-2020-006 in the wild and no public exploit code.

Affected product: drupal/saml_sp. 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.
