CVE-2022-35925Public exploitNetwork attack vector

Account compromise via unthrottled authentication requests

Published Aug 2, 2022 · Updated Apr 22, 2025

Missing rate limiting in BookWyrm before 0.4.5 allows remote attackers to brute-force authentication endpoints over the network. The Nginx configuration proxies /login, /password-reset, and /resend-link without a limit_req rule or per-address request-rate zone. No account or user interaction is required to send repeated requests; successful password guessing grants only the compromised account's privileges.
