GHSA-f884-gm86-cg3q
Fix: PrestaShop/ps_facetedsearch@47c4785GHSA-f884-gm86-cg3q is a remote code execution vulnerability in prestashop/ps_facetedsearch. O3 Security confirms whether GHSA-f884-gm86-cg3q is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
PrestaShop module ps_facetedsearch might be vulnerable from CVE-2017-9841
Real-World Exposure
prestashop/ps_facetedsearchReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
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
- 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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for prestashop/ps_facetedsearch. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update prestashop/ps_facetedsearch to 3.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f884-gm86-cg3q is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-f884-gm86-cg3q is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-f884-gm86-cg3q. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-f884-gm86-cg3q in your dependencies?
O3 detects GHSA-f884-gm86-cg3q across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
