Vulnerability details

Impact

Function _isValidGovernor() is not about pause/unpause but about msg.sender being valid Governor, which is used by setAdmin/setGlobals in LoanFactory.sol.

Therefore, the Natspec comment for this function is incorrect: @dev Function to determine if msg.sender is eligible to trigger pause/unpause.

Proof of Concept
