All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 3m22s
Critical: Add ownership checks to all order routes (IDOR fix). High: Redis rate limiting on auth endpoints, HMAC-signed internal service calls replacing header-presence-only checks, nh3 HTML sanitization on ghost_sync and product import, internal auth on market API endpoints, SHA-256 hashed OAuth grant/code tokens. Medium: SECRET_KEY production guard, AP signature enforcement, is_admin param removal, cart_sid validation, SSRF protection on remote actor fetch.

"""Internal action client for cross-app write operations.
|
|
|
|
Each coop app exposes JSON action endpoints at ``/internal/actions/{name}``.
|
|
This module provides helpers to call those endpoints so that callers don't
|
|
need direct access to another app's DB session or service layer.
|
|
|
|
Failures raise ``ActionError`` so callers can handle or propagate them.
