Authenticated code execution via unsandboxed webhook templates
Published Dec 17, 2025 · Updated Dec 17, 2025
Server-side template injection in Crafty Controller 4.6.1 allows remote authenticated users to execute code through webhook templates. The Webhook Template component renders attacker-controlled Jinja expressions with a generic Environment that permits access to unsafe Python built-ins instead of an immutable sandbox. Access to create or edit webhooks is required, and successful exploitation runs commands with the Crafty service account's host privileges.
