No affected components available
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.
Patch: https://github.com/aio-libs/aiohttp/commit/bf88077ebb14f4c29924b8e8904cba20c55c28b8
