Summary
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.
Exploit prediction (EPSS)
0.80% probability of exploitation in the next 30 days, higher than 57% of all scored CVEs.
