Business logic vulnerability testing detects design flaws in application processes like workflow bypass, price manipulation, quantity limit circumvention, and time-based race conditions in transaction processing.

Test for race conditions in API transaction processing by analyzing concurrent operations and unauthorized state transitions. This validates security by identifying time-based exploitation opportunities in financial operations.

Detect workflow bypass and price manipulation by analyzing API requests and state transitions. This identifies design flaws allowing users to skip validation steps or tamper with negative pricing in order management.

Yes, this skill identifies quantity limit circumvention by analyzing API requests and state transitions in purchase APIs. It detects design flaws allowing users to bypass quantity restrictions in order management.

The best way to test for unauthorized state changes is by analyzing state transitions and concurrent operations. This validates security by exposing concurrency exploitation and workflow bypass vulnerabilities in transaction processing.

Business logic testing focuses on design flaws because vulnerabilities in transaction processing and order management workflows can lead to unauthorized actions, data manipulation, and financial losses without requiring code injection.
