A comprehensive playbook for advanced security testing, focusing on race conditions and TOCTOU (Time-of-check to time-of-use) vulnerabilities in web applications. It guides users to exploit non-atomic, state-changing operations (e.g., coupons, balance deductions, single-use rewards) by sending highly synchronized, parallel requests (including HTTP/2 single-packet attacks). Essential for identifying weaknesses in authorization and transactional integrity.
