Permits may be reused after token upgrade

Lines of code Vulnerability details Impact The StandardizedToken contract inherits the ERC20Permit contract which in the case of an upgradable/proxied Token would allow permits for a previous version of the Token to be used on any subsequent version of it. NOTE that ERC20Permit is not explicitly ...

balance of the recipient to is updated after the token transfer (safeTransferFrom function) could lead to reentrancy attack

Lines of code Vulnerability details Impact The balance of the recipient to is updated after the token transfer safeTransferFrom function. If the safeTransferFrom function triggers an external contract, and that contract, in turn, calls back to this contract, it can result in a reentrancy attack...

Reentrant Call Vulnerability in ExpressCallHandler Contract

Lines of code Vulnerability details DISCRIPTION The ExpressCallHandler contract contains a potential bug related to handling the express calls. The issue lies in the setExpressReceiveToken and setExpressReceiveTokenWithData functions. Specifically, these functions don't properly handle reentrant...

bypass flow limit by transferring tokens at epoch's boarder

Lines of code Vulnerability details Impact Token flow can reach 2flowlimit in a very short time. Proof of Concept We store the flow out and flow in tokens numbers for every epoch: / @dev Returns the slot which is used to get the flow out amount for a specific epoch @param epoch The epoch to get t...

sendToken() shouldn't have metadata parameter

Lines of code Vulnerability details Impact Users calling sendToken with metadata may trigger a revert or lose the calldata if its size is 1-3 bytes when the destination is an EOA. Proof of Concept In transmitSendToken, we discard the calldata if it's less than 4 bytes, and revert if it's bigger o...

Replay Attack Vulnerability Due to Uniqueness Invariant Violation in AxelarServiceGovernance Contract's Proposal Hash Generation

Lines of code Vulnerability details Impact The current implementation of the AxelarServiceGovernance contract relies solely on the Keccak256 algorithm to generate proposal hashes, using only the target contract's address, encoded function call data, and the native token transfer value as...

funds can be stolen in InterchainGovernance, Multisig and AxelarServiceGovernance contracts

Lines of code Vulnerability details Impact In InterchainGovernance users can execute the proposal by passing required data and the amount of native value they want to send with executeProposal function, this function calls call function in Caller contract, but this function insted of checking...

MultisigBase.sol : Unsafe onlySigners modifier

Lines of code Vulnerability details Impact The multi sig based implementation will not serve its purpose. Proposals can be executed even by a single signer. Proof of Concept Contract has the MultisigBase implementation which will be used as a custom multisignature wallet where transactions must b...
