Summary
Logto bypasses OIDC nonce validation when the nonce claim is absent from the id_token, enabling replay of authentication tokens and weakening session-binding.
Risk Assessment
The risk is that authentication tokens can be replayed, leading to unauthorized session access.
Recommendation
Upgrade Logto to a version that enforces nonce validation even when absent from the id_token.
