As published by the source; long descriptions are shortened.

Impact We have identified that some psfacetedsearch 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 - 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, 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.

# Patch Next advisory brief: GHSA-f884-gm86-cg3q

Advisory: PrestaShop module ps_facetedsearch might be vulnerable from CVE-2017-9841
IDs: GHSA-f884-gm86-cg3q
Record: https://patchnext.com/advisories/ghsa-f884-gm86-cg3q (revision 1, source checked 26 Oct 2026, 13:56 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: prestashop/ps_facetedsearch 3.4.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist prestashop/ps_facetedsearch: affected < 3.4.1; fixed in 3.4.1

## Suggested inspection (read-only)
- Packagist prestashop/ps_facetedsearch: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on prestashop/ps_facetedsearch.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-f884-gm86-cg3q (GitHub-reviewed advisory GHSA-f884-gm86-cg3q lists affected ranges: Packagist prestashop/ps_facetedsearch >=0 <3.4.1)
