How to fix?
github.com/crypto-org-chain/cronos to version 0.6.5 or higher.
github.com/crypto-org-chain/cronos is a Crypto.org EVM Chain which aims to massively scale the DeFi ecosystem. It is powered by Ethermint, a scalable and interoperable Ethereum, built on Proof-of-Stake with fast-finality using the Cosmos SDK.
Affected versions of this package are vulnerable to Always-Incorrect Control Flow Implementation as it is possible to take transaction fees from Cosmos SDK's FeeCollector for the current block by sending a custom crafted MsgEthereumTx.
User funds and balances are safe.
