Zipline 4.3.2 before 4.8.0 contains a rate limit bypass vulnerability that allows unauthenticated attackers to evade throttling by spoofing X-Forwarded-For headers when core.trustProxy is enabled. Attackers can send a different X-Forwarded-For value per request to obtain fresh rate-limit buckets, enabling unlimited guessing of login passwords, TOTP codes, and file and URL passwords.
