Overview

github.com/ory/fosite is an OAuth2 & OpenID Connect framework for Go.

Affected versions of this package are vulnerable to Improper Authentication. When using "private_key_jwt" authentication the uniqueness of the jti value is not checked. When using client authentication method "private_key_jwt", OpenId specification says the following about assertion jti: "A unique identifier for the token, which can be used to prevent reuse of the token. These tokens MUST only be used once, unless conditions for reuse were negotiated between the parties". Hydra does not seem to check the uniqueness of this jti value.
