## What is DRUPAL-CONTRIB-2023-033?

DRUPAL-CONTRIB-2023-033 is a code injection vulnerability in drupal/matomo, published on 2 Aug 2023. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

This module enables you to add the Matomo web statistics tracking system to your website.

The module does not check the Matomo JS code loaded on the website. So a user could configure the module to load JS from a malicious website.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer matomo" or "administer matomo tag manager" (D8+ only) to access the settings forms where this can be configured.

What it is: DRUPAL-CONTRIB-2023-033 is a code injection vulnerability in drupal/matomo, published on 2 Aug 2023. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2023-033 in the wild and no public exploit code.

Affected product: drupal/matomo. 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.
