MetaProtocol.swapBack() (#583-631) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#613)
- (tmpSuccess,None) = address(teamFeeReceiver).call{gas: 30000,value: amountBNBTeam}() (#614)
- (tmpSuccess,None) = address(charityFeeReceiver).call{gas: 30000,value: amountBNBCharity}() (#615)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
