CYM [CYLUM] Token

Contract creator or owner is blacklisted for past scams

CYLUM.withdrawStuckToken(address,address) (#658-661) ignores return value by IERC20(token).transfer(recipient,IERC20(token).balanceOf(address(this))) (#660)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract ownership is not renounced (belongs to a wallet)

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#402-423):
- (success,returndata) = target.call{value: weiValue}(data) (#406)
Low level call in Address.sendValue(address,uint256) (#336-342):
- (success) = recipient.call{value: amount}() (#340)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
