BNBSWAPToken.transferToAddressETH(address,uint256) (#973-975) sends eth to arbitrary user
Dangerous calls:
- recipient.transfer(amount) (#974)
BNBSWAPToken.airdrop(address) (#1046-1059) sends eth to arbitrary user
Dangerous calls:
- address(address(uint160(_refer))).transfer(referEth) (#1055)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
