CWE-1086: Class with Excessive Number of Child Classes
A class contains an unnecessarily large number of children.
How it's found
Class with Excessive Number of Child Classes is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
While the interpretation of "large number of children" may vary for each product or developer, CISQ recommends a default maximum of 10 child classes.
Consequences
- Reduce Maintainability, Increase Analytical Complexity: This issue makes it more difficult to understand and maintain the software, 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.
Where this fits in a TurboPentest engagement
TurboPentest's agentic pentest is powerful and covers a broad range of issues automatically. This particular class is best confirmed in a manual IntegSec engagement, where human pentesters apply deeper methodology and a larger context window than any automated pass.
