Authentication Bypass

PyHawk is a Python libraries for the 'HAWK' HTTP authentication scheme

Affected versions of this package are vulnerable to Authentication Bypass. The incoming (client supplied) hash of the payload is trusted by the server and not verified before the signature is calculated.

A malicious actor in the middle can alter the payload and the server side will not identify the modification occurred because it simply uses the client provided value instead of verify the hash provided against the modified payload.

According to the maintainers this issue is to be considered out of scope as "payload hash validation is optional and up to developer to implement".
