Description
Shopware is an open source commerce platform based on Symfony Framework and Vue js. In affected versions It was possible to put the same line item multiple times in the cart using the AP. The Cart Validators checked the line item's individuality and the user was able to bypass quantity limits in sales. This problem has been fixed with version 6.4.18.1. Users on major versions 6.1, 6.2, and 6.3 may also obtain this fix via a plugin.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for shopware/platform. 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 shopware/platform to 6.4.18.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-22730 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-2023-22730 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-2023-22730. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
