CVE-2022-45196: Hyperledger Fabric

High severity, CVSS 7.5. EPSS: 0.9% chance of exploitation in the next 30 days.

Hyperledger Fabric 2.3 allows attackers to cause a denial of service (orderer crash) by repeatedly sending a crafted channel tx with the same Channel name. NOTE: the official Fabric with Raft prevents exploitation via a locking mechanism and a check for names that already exist.
