Vulnerability Details

function convertToUsdValue(
GMXTypes.Store storage self,
address token,
uint256 amt
  ) public view returns (uint256) {
   return amt * 10**(18 - IERC20Metadata(token).decimals())
            * self.chainlinkOracle.consultIn18Decimals(token)
            / SAFE_MULTIPLIER;
  }

as can see, due to this 10**(18 - IERC20Metadata(token).decimals()), that it doesn’t work with tokens that have more than 18 decimal places
