Description
AVideo API fails to enforce rate limits when clients send a bot User-Agent header, allowing attackers to bypass all eight protected operations including login brute-force protection. Attackers can send requests with a bot User-Agent to disable rate limiting and perform unlimited password guessing attempts against any account from a single IP address.
