Open the reportLowPotential Cross-chain Replay AttackGrabCoinClub · CertiK · 12 Oct 2022Open
Within the current contract, there is no distinction between the different blockchains supported by `GrabCoinClub`. If the signer signed a message on one chain (e.g. Ethereum), and accidentally leaks the message, the message would be valid for a similar transaction of a chain with the same encryption method (e.g. BSC). For example, if the signer signed a message (wallet_, series_, quantity_, tokenAddress_, amount_, nonce_) on Ethereum and the same wallet_, tokenAddress_ exists on BSC. The attacker can reuse this signed message to mint NFT on BSC.
