## What is GHSA-m9fv-whq2-6wmc?

GHSA-m9fv-whq2-6wmc is a vulnerability in drupal/drupal, published on 15 May 2024. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The Drupal project uses the third-party library [Archive_Tar](https://pear.php.net/package/Archive_Tar/), which has released a security improvement that is needed to protect some Drupal configurations.

Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2 or .tlz file uploads and processes them.

The latest versions of Drupal update Archive_Tar to 1.4.9 to mitigate the file processing vulnerabilities.

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.
