MISSB [MissBeijing] Token

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

MissBeijing.addLiquidity(uint256,uint256) (#1268-1284) sends eth to arbitrary user
Dangerous calls:
- (ethFromLiquidity) = uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#1274-1281)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
