GHSA-gqcf-83rq-gpfr
Any storage file can be downloaded from p.sh if full server path is known
Blast Radius
ibexa/post-installReal-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
The default configuration for platform.sh (.platform.app.yaml) allows access to uploaded files if you know or can guess their location, regardless of whether roles grant content read access to the content containing those files. If you're using Legacy Bridge, the default configuration also allows access to certain legacy files that should not be readable, including the legacy var directory and extension directories.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | ibexa/post-install | all versions | 1.0.4.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ibexa/post-install. 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 ibexa/post-install to 1.0.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gqcf-83rq-gpfr 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-gqcf-83rq-gpfr 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-gqcf-83rq-gpfr. 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-gqcf-83rq-gpfr in your dependencies?
O3 detects GHSA-gqcf-83rq-gpfr across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
