Description
PrestaShop is an Open Source e-commerce web application. Versions prior to 8.0.4 and 1.7.8.9 contain a SQL filtering vulnerability. A BO user can write, update, and delete in the database, even without having specific rights. PrestaShop 8.0.4 and 1.7.8.9 contain a patch for this issue. There are no known workarounds.

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 8.0.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-30839 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 CVE-2023-30839 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 CVE-2023-30839. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
