Summary

Attacker-controlled input included into multipart/payload headers can be used to modify a request to inject additional headers or similar.

Impact

In the unlikely situation that an application is passing user-controlled strings into MultipartWriter.append(headers=...) or Payload.headers, then an attacker may be able to modify the request to inject headers or change the contents of the request.

Workaround

Sanitise such user input.
