Impact
We fixed with CVE-2023-22731 Twig filters to only be executed with allowed functions. It is possible to pass PHP Closures as string or an array and array crafted PHP Closures was not checked against allow list
Patches
The problem has been fixed with 6.4.20.1 with an improved override.
Workarounds
For older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.
Is GHSA-7v2v-9rm4-7m8f in any of your client repos?
Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected shopware/platform, and gives you the command that fixes it.
