Submission Details
Severity:
ether balance can not be withdrawn
Summary
User can signup with ether, but ether can not be withdrawn by host.
Vulnerability Details
In the withdraw function:
function withdraw() external onlyHost {
address _host = getHost();
i_WETH.safeTransfer(_host, i_WETH.balanceOf(address(this)));
i_WBTC.safeTransfer(_host, i_WBTC.balanceOf(address(this)));
i_USDC.safeTransfer(_host, i_USDC.balanceOf(address(this)));
}
no ether will be transfered to host.
Impact
Ether will be locked in the contract.
Recommendations
Just add ether transfer logic
function withdraw() external onlyHost {
address _host = getHost();
i_WETH.safeTransfer(_host, i_WETH.balanceOf(address(this)));
i_WBTC.safeTransfer(_host, i_WBTC.balanceOf(address(this)));
i_USDC.safeTransfer(_host, i_USDC.balanceOf(address(this)));
+ payable(_host).transfer(address(this).balance);
}
