Zipline before 4.6.4 contains a rate limit bypass vulnerability that allows remote attackers to evade request limits by varying query strings or supplying the x-zipline-p-filename header. Attackers can append differing query parameters to login and file or short-link password verification endpoints to perform credential guessing beyond the intended rate limits.
