CWE-691: Insufficient Control Flow Management
The code does not sufficiently manage its control flow during execution, creating conditions in which the control flow can be modified in unexpected ways.
How it's found
Insufficient Control Flow Management is a broad weakness category rather than one exact bug. Testers narrow it down through manual code review and architecture review to identify which of its more specific child weaknesses actually appears in a given target, then confirm each one individually.

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.
