the protocol interest update 12 hours can cause problem

Summary

the contract erc20pool uses updateinterest function which updates interest after 12 hours and if protocol is paused the borrowers should pay more interest than real interest

Vulnerability Detail

Impact

users pays unnecessary money to protocol

Code Snippet

        PoolState memory poolState_,
        uint256 lup_
    ) internal {
        // if it has been more than 12 hours since the last interest rate update, call updateInterestRate function
       if (block.timestamp - interestState.interestRateUpdate > 12 hours) {
            PoolCommons.updateInterestRate(interestState, deposits, poolState_, lup_);
        }

        // update pool inflator
        if (poolState_.isNewInterestAccrued) {
            inflatorState.inflator       = uint208(poolState_.inflator);
            inflatorState.inflatorUpdate = uint48(block.timestamp);
        // if the debt in the current pool state is 0, also update the inflator and inflatorUpdate fields in inflatorState
        // slither-disable-next-line incorrect-equality
        } else if (poolState_.debt == 0) {
            inflatorState.inflator       = uint208(Maths.WAD);
            inflatorState.inflatorUpdate = uint48(block.timestamp);
        }
    } ```
