CVE-2023-42806
Hydra is the layer-two scalability solution for Cardano. Prior to version 0.13.0, not signing and verifying $\mathsfcid$ allows an attacker which must be a participant of this head to use a snapshot from an old head instance with the same participants to close the head or contest the state with i...
CVE-2023-42448
Hydra is the layer-two scalability solution for Cardano. Prior to version 0.13.0, the specification states that the contestation period in the datum of the UTxO at the head validator must stay unchanged as the state progresses from Open to Closed Close transaction, but no such check appears to be...
