In ORY Fosite (the security first OAuth2 & OpenID Connect framework for Go) before version 0.31.0, 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. This problem is fixed in version 0.31.0.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
