## What is DRUPAL-CONTRIB-2021-033?

DRUPAL-CONTRIB-2021-033 is a command injection vulnerability in drupal/file_extractor, published on 22 Sep 2021. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

This module enables you to extract the textual content of files for use on a website, e.g. to display it or use it in search indexes.

The module doesn't sufficiently protect the administrator-defined commands that are executed on the server, which leads to post-authentication remote code execution by a limited set of users.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer File Extractor" to access the settings form. Sites are encouraged to review which roles have that permission and which users have that role, to ensure that only trusted users have that permission.

Check this codebase for DRUPAL-CONTRIB-2021-033 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2021-033 is a command injection vulnerability in drupal/file_extractor, published on 22 Sep 2021. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2021-033 in the wild and no public exploit code.

Affected product: drupal/file_extractor. 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.
