Summary
Authentication bypass by capture-replay in github.com/cosmos/ethermint
Details

Cosmos Network Ethermint <= v0.4.0 is affected by a cross-chain transaction replay vulnerability in the EVM module. Since ethermint uses the same chainIDEpoch and signature schemes with ethereum for compatibility, a verified signature in ethereum is still valid in ethermint with the same msg content and chainIDEpoch, which enables "cross-chain transaction replay" attack.

Specific Go Packages Affected

Severity ?
7.5 (High)
