SQKG [Squid King] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

SquidKing.swapETHForRewards(address) (#1323-1339) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: address(this).balance}(0,path,recipient,block.timestamp.add(300)) (#1333-1338)
SquidKing.addLiquidity(uint256,uint256) (#1341-1355) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#1347-1354)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
