AVAXXINE.swapBack() (#871-907) sends eth to arbitrary user
Dangerous calls:
- distributor.deposit{value: amountBNBReflection}() (#898)
AVAXXINE._addLiquidity(uint256,uint256) (#909-924) sends eth to arbitrary user
Dangerous calls:
- (tokenAmountSent,ethAmountSent,liquidity) = router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,DEAD,block.timestamp) (#914-921)
AVAXXINE.transferToAddressBNB(address,uint256) (#930-932) sends eth to arbitrary user
Dangerous calls:
- recipient.transfer(amount) (#931)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
