ID Name Description Links
CWE-441 Unintended Proxy or Intermediary ('Confused Deputy') The software receives a request, message, or directive from an upstream component, but the software does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the software's control sphere. This causes the software 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. CVE
