## What is GHSA-f884-gm86-cg3q?

GHSA-f884-gm86-cg3q is a code injection vulnerability in prestashop/ps_facetedsearch, published on 7 Jan 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

### Impact

We have identified that some ps_facetedsearch module ZIP archives have been built with phpunit dev dependencies. PHPUnit contains a php script that would allow, on a webserver, an attacker to perform a RCE.

This vulnerability impacts
- phpunit before 4.8.28 and 5.x before 5.6.3 as reported in [CVE-2017-9841](https://nvd.nist.gov/vuln/detail/CVE-2017-9841)
- phpunit >= 5.63 before 7.5.19 and 8.5.1 (this is a newly found vulnerability that is currently being submitted as a CVE after disclosure was provided to phpunit maintainers)

### Patches

In the [security patch](https://github.com/PrestaShop/ps_facetedsearch/releases/tag/v3.4.1), we look for the unwanted vendor/phpunit folder and remove it if we find it. This allows users to fix the security issue when upgrading.

### Workarounds
Users can also simply remove the unwanted vendor/phpunit folder.

What it is: GHSA-f884-gm86-cg3q is a code injection vulnerability in prestashop/ps_facetedsearch, published on 7 Jan 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of GHSA-f884-gm86-cg3q in the wild and no public exploit code.

- prestashop/ps_facetedsearch (Packagist): affected all versions; fixed in 3.4.1

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.
