CWE-1124

Excessively Deep Nesting. [Complexity-Issues, Improper-Adherence-To-Coding-Standards]

Required inputs: IR

The code contains a callable or other code grouping in which the nesting / branching is too deep.

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.
