Relayer/executor-already-set Error in CrossChainRelayerArbitrum Contract

Lines of code Vulnerability details Summary The setExecutor function in the CrossChainRelayerArbitrum contract improperly reverts when the executor variable has already been set. Impact This bug could prevent the CrossChainRelayerArbitrum contract from properly setting the executor variable,...

Relayed calls in EthereumToArbitrumRelayer can be replayed

Lines of code Vulnerability details Impact A relayed call can be processed multiple times allowing somebody to execute the user's call multiple times. The bridge allows arbitrary calls to contracts. Depending on the nature of the call, this could result in a loss of funds for the user. Proof of...

Atomicity Literally NOT Guaranteed
