GitHub Security Advisory
Shopware vulnerable to Server Side Template Injection in Twig using deprecation silence tag
✓ GitHub Reviewed
HIGH
Has CVE
Advisory Details
### Impact
Shopware has a new Twig Tag `sw_silent_feature_call` which silences deprecation messages while triggered in this tag.
It accepts as parameter a string the feature flag name to silence, but this parameter is not escaped properly and allows execution of code.
### Patches
Update to Shopware 6.6.5.1 or 6.5.8.13
### Workarounds
For older versions of 6.2, 6.3, and 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.
