AI-suggested
Users should monitor the vendor's advisory channels for updates. Until a fix is released, consider implementing external protections such as web application firewalls (WAF) with rate limiting rules or reverse proxies that can throttle repeated login attempts. Avoid relying solely on the application to prevent brute-force attacks.
Description
changedetection.io's /login route checks the submitted password against a single PBKDF2-HMAC-SHA256 hash with no per-IP or per-session rate limiting, failed-attempt counter, or lockout (no rate-limiting library is present in requirements.txt).
