Race conditions in authentication logic manifest as an attacker sending multiple concurrent requests at the same time, exploiting the time gap between the server's check and execution to bypass limits; the key to defense is for the server to use atomic operations (such as database row locks, unique constraints, or Redis SETNX) to ensure the atomicity of "check-then-execute."
