Technical details

The vulnerability stems from a hardcoded default app_secret ("change-me-in-development") in config.py used to sign HMAC-SHA256 tokens. An unauthenticated attacker can craft a valid token for the default 'admin' user in the 'tenant_demo' tenant by reproducing the token generation logic in auth.py with the known secret, bypassing authentication entirely. This grants full tenant administration including access to model and channel credentials stored in the database.
