Common Weakness Enumeration
- CWE-441 - Unintended Proxy or Intermediary ('Confused Deputy')The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor.
- CWE-610 - Externally Controlled Reference to a Resource in Another SphereThe product uses an externally controlled name or reference that resolves to a resource that is outside of the intended control sphere.
