### 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.

What it is: DRUPAL-CORE-2019-012 is a vulnerability in drupal/core, published on 18 Dec 2019. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of DRUPAL-CORE-2019-012 in the wild and no public exploit code.

Affected packages and fixed versions:
- drupal/core (Packagist): affected from 8.0.0; fixed in 8.7.11, 8.8.1

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.
