WToken.swapAndLiquify(uint256) (contracts/WToken.sol#416-440) sends eth to arbitrary user
Dangerous calls:
- (successProject) = projectAddress.call{value: newBalance.mul(_projectFee).div(_fundingFee + _liquidityFee + _projectFee)}() (contracts/WToken.sol#426)
- (successFunding) = fundingAddress.call{value: newBalance.mul(_fundingFee).div(_fundingFee + _liquidityFee + _projectFee)}() (contracts/WToken.sol#431)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

- (successProject) = projectAddress.call{value: newBalance.mul(_projectFee).div(_fundingFee + _liquidityFee + _projectFee)}() (contracts/WToken.sol#426)
- (successFunding) = fundingAddress.call{value: newBalance.mul(_fundingFee).div(_fundingFee + _liquidityFee + _projectFee)}() (contracts/WToken.sol#431)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
