Medium. Issues that do not lead to a loss of funds directly, but break the contract logic. May lead to failures in contracts operation.

Low. Issues that are of a non-optimal code character, for instance, gas optimization tips, unused variables, errors in messages.

Info. Issues that do not impact the contract operation. Usually, info severity issues are related to code best practices, e.g. style guide.
