DeVolution.addLiquidity(uint256,uint256) (Devolution.sol#413-426) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(liquidityWallet),block.timestamp) (Devolution.sol#418-425)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
