CWE-480: Use of Incorrect Operator
The product accidentally uses the wrong operator, which changes the logic in security-relevant ways.
How it's found
Use of Incorrect Operator 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.
These types of errors are generally the result of a typo by the programmer.

- Alter Execution Logic: This weakness can cause unintended logic to be executed and other unexpected application behavior.
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.
