Multiple Inheritance from Concrete Classes. [Complexity-Issues, Improper-Adherence-To-Coding-Standards]

The product contains a class with inheritance from more than one concrete class.

This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
