No access control

Summary

There is no onlyAdmin modifier in the updateChainLinkCollateralPrice and amoMinterBorrow.

Vulnerability Detail

function updateChainLinkCollateralPrice(uint256 collateralIndex) external { LibUbiquityPool.updateChainLinkCollateralPrice(collateralIndex); }

function amoMinterBorrow(uint256 collateralAmount) external { LibUbiquityPool.amoMinterBorrow(collateralAmount); }

Impact

Any one calls this function and update the function?

Invalid

  1. updateChainLinkCollateralPrice() - Does not require access control, simply updates price to update to date chainlink price, which will benefit all users
  2. amoMinterBorrow() - relevant acces control is already checked here, wherein the caller must be a enabled amo by the admin
