Last modified
CVE-2022-45196 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 0.80% chance of exploitation in the next 30 days.
