CVE-2026-102334

Nginx Proxy Manager through 2.16.0 Missing Brute-Force Protection

Nginx Proxy Manager through 2.16.0 lacks rate-limiting on authentication endpoints, allowing unauthenticated attackers to make unlimited password guesses against any account. Attackers can brute-force login credentials via POST /api/tokens and subsequently guess TOTP codes via POST /api/tokens/2fa to gain full session access and administrative control.
