HUNGER Token

HungerToken.__buybackAndBurn(uint128,uint256) (HungerToken.sol#910-932) sends eth to arbitrary user
Dangerous calls:
- _pancakeRouter.swapExactETHForTokensSupportingFeeOnTransferTokens{value: buybackBNB}(0,path,_burnAddress,block.timestamp) (HungerToken.sol#923-930)
HungerToken.__addLiquidity(uint256,uint256) (HungerToken.sol#934-966) sends eth to arbitrary user
Dangerous calls:
- _pancakeRouter.addLiquidityETH{value: bnbAmount}(address(this),tokenQuote,0,0,address(this),block.timestamp) (HungerToken.sol#955-962)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
