vulnerability
Security researcher discovered two critical bugs in Cronos Gravity Bridge: (1) an incorrect ERC-20 deploy event check causing nonce mismatch that halts cross-chain transfers from Ethereum to Cronos, and (2) a malicious token that can disable the entire bridge. The vulnerabilities stem from inadequate validation in the MsgSubmitEthereumEvent handler and token supply checks.
