| CVE-2022-36023 | 1 Hyperledger | 1 Fabric | 2023-02-15 | N/A | 5.3 MEDIUM |
| Hyperledger Fabric is an enterprise-grade permissioned distributed ledger framework for developing solutions and applications. If a gateway client application sends a malformed request to a gateway peer it may crash the peer node. Version 2.4.6 checks for the malformed gateway request and returns an error to the gateway client. There are no known workarounds, users must upgrade to version 2.4.6. | |||||
| CVE-2022-45196 | 1 Hyperledger | 1 Fabric | 2022-11-17 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2022-31121 | 1 Hyperledger | 1 Fabric | 2022-07-15 | 5.0 MEDIUM | 7.5 HIGH |
| Hyperledger Fabric is a permissioned distributed ledger framework. In affected versions if a consensus client sends a malformed consensus request to an orderer it may crash the orderer node.

Users are advised to upgrade to versions 2.2.7 or v2.4.5. There are no known workarounds for this issue. | |||||

| Hyperledger Iroha versions v1.0_beta and v1.0.0_beta-1 are vulnerable to transaction and block signature verification bypass in the transaction and block validator allowing a single node to sign a transaction and/or block multiple times, each with a random nonce, and have other validating nodes accept them as separate valid signatures. | |||||
