Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Race conditions occur when multiple concurrent requests exploit the brief time gap between checking a condition and acting upon it (TOCTOU - Time of Check, Time of Use).
