In the OAuth library for nim prior to version 0.11, the state values generated by the generateState function do not have sufficient entropy. These can be successfully guessed by an attacker allowing them to perform a CSRF vs a user, associating the user's session with the attacker's protected resources. While state isn't exactly a cryptographic value, it should be generated in a cryptographically secure way. generateState should be using a CSPRNG. Version 0.11 modifies the generateState function to generate state values of at least 128 bits of entropy while using a…Read More
