Description
Shopware is an open commerce platform. Prior to versions 6.6.5.1 and 6.5.8.13, the context variable is injected into almost any Twig Template and allows to access to current language, currency information. The context object allows also to switch for a short time the scope of the Context as a helper with a callable function. The function can be called also from Twig and as the second parameter allows any callable, it's possible to call from Twig any statically callable PHP function/method. It's not possible as customer to provide any Twig code, the attacker would require access to Administration to exploit it using Mail templates or using App Scripts. Update to Shopware 6.6.5.1 or 6.5.8.13 to receive a patch. For older versions of 6.1, 6.2, 6.3 and 6.4 corresponding security measures are also available 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/core. 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/core to 6.5.8.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-42356 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-2024-42356 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-2024-42356. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
