Emergency withdrawals can not be stopped

s4muraii77

Summary

Emergency withdrawals can not be stopped

Vulnerability Details

Emergency withdrawals can be activated with the code below:

function enableEmergencyWithdraw() external onlyOwner withEmergencyDelay(EMERGENCY_WITHDRAW_ACTION) {
emergencyWithdrawDelay = block.timestamp + EMERGENCY_DELAY;
emit EmergencyWithdrawEnabled(emergencyWithdrawDelay);
​
}

Then, emergencyWithdraw() can be called with the following condition:

if (emergencyWithdrawDelay == 0 || block.timestamp < emergencyWithdrawDelay) revert EmergencyWithdrawNotEnabled();

The emergency withdraw delay must be set and we must be after that timestamp for the function to work. The issue is that emergencyWithdrawDelay can never be removed which means that once the delay passes, emergency withdrawals (which allow withdrawing before the lock's end) will always be possible.

Impact

Withdrawals will be always possible immediately once the delay has been set, no way to remove it.
