Technical details

The backend unconditionally trusts the X-Forwarded-For proxy header in main.ts via the "trust proxy" setting, allowing attackers to rotate spoofed client IP addresses. An attacker can send repeated authentication attempts against /api/auth/signIn, /api/auth/signIn/totp, and /api/auth/resetPassword endpoints without triggering per-IP rate limiting, enabling credential brute-force attacks and TOTP code enumeration.
