FastAPI Api Key has a timing side-channel in verify_key that allows statistical key validity detection

Impact Timing side-channel vulnerability in verifykey. The method applied a random delay only on verification failures, allowing an attacker to statistically distinguish valid from invalid API keys by measuring response latencies. With enough repeated requests, an adversary could infer whether a...
