## What is DRUPAL-CONTRIB-2019-048?

### Official description

This module enables you to use special routes for user registration with special roles and custom field sets defined for the role.

The module doesn't sufficiently check which user roles can be registered under the scenario when the user tries to register the user with the administrator role.

This vulnerability is mitigated on sites where account approval is required as the user starts as blocked but still gets the "Administrator" role.

Check this codebase for DRUPAL-CONTRIB-2019-048 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2019-048 is a vulnerability in drupal/multiple_registration, published on 15 May 2019. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2019-048 in the wild and no public exploit code.

Affected product: drupal/multiple_registration. 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.
