CVE-2026-111934 · Coder before 2.34.7 IP Spoofing via X-Forwarded-For Header
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Coder before 2.34.7 contains an IP spoofing vulnerability in the ExtractRealIPAddress middleware that trusts the leftmost, client-supplied X-Forwarded-For value instead of the client IP appended by a reverse proxy. Attackers can send forged X-Forwarded-For values through appending proxies to bypass per-IP rate limits on login, one-time passcode, and password validation endpoints, enabling brute-force attacks, and to falsify IP addresses recorded in audit logs.
