## What is DRUPAL-CONTRIB-2021-035?

DRUPAL-CONTRIB-2021-035 is a missing authorization vulnerability in drupal/taxonomy_manager, published on 22 Sep 2021. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This module provides a powerful interface for managing a taxonomy vocabulary. A vocabulary gets displayed in a dynamic tree view, where parent terms can be expanded to list their nested child terms or can be collapsed.

The module does not take the correct user permissions into account, allowing an attacker to delete and move terms.

The issue is mitigated by the fact that an attacker must have permission to create terms in the targeted vocabulary.

Affected product: drupal/taxonomy_manager. 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.
