Two Critical Bugs in Shopware's App System

25 August 2026

I found two critical bugs in Shopware 6. One is a sandbox escape in App Scripts, one is a stored SQL injection through custom entities. Both break the same trust boundary: the App. Reported, fixed, credited, and now public. No exploit details.
