GHSA-7pjr-2rgh-fc5g is a medium-severity (CVSS 5.3) Information Exposure vulnerability in prestashop/prestashop. O3 Security confirms whether GHSA-7pjr-2rgh-fc5g is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Anonymous PrestaShop customer can download other customers' invoices
Real-World Exposure
prestashop/prestashopReal-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
Since PrestaShop 8.1.5, any invoice can be downloaded from front-office in anonymous mode, by supplying a random secure_key parameter in the url.
Patches
Patched in 8.1.6
Workarounds
Upgrade to 8.1.6
Thank you to Samuel Bodevin, who found this vulnerability and shared it with the PrestaShop team.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for prestashop/prestashop. 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/prestashop to 8.1.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7pjr-2rgh-fc5g 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-7pjr-2rgh-fc5g 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-7pjr-2rgh-fc5g. 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-7pjr-2rgh-fc5g in your dependencies?
O3 detects GHSA-7pjr-2rgh-fc5g across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
