CVE-2026-102335 High · 7.1 CWE-863 Sep 28, 2026

Nginx Proxy Manager through 2.16.0 Improper Authorization via advanced_config

Nginx Proxy Manager through 2.16.0 fails to restrict the advanced_config field to administrators, allowing non-admin users with manage permissions to inject arbitrary nginx directives. Attackers can inject malicious nginx configuration such as alias directives to serve arbitrary files or control routing for their assigned hosts.

CVE-2026-102334 High · 7.4 CWE-307 Sep 28, 2026

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.

CVE-2026-93964 Medium · 5.3 CWE-287 Sep 20, 2026

NginxProxyManager nginx-proxy-manager Validate Route certificate.js internalCertificate.validate missing authentication

A vulnerability was detected in NginxProxyManager nginx-proxy-manager up to 2.15.1. This impacts the function internalCertificate.validate of the file backend/internal/certificate.js of the component Validate Route. The manipulation results in missing authentication. The attack can be launched remotely. The exploit is now public and may be used. Endpoint only processes and echoes back the certificate the caller submits (no stored data leaked); the real risk is unauthenticated openssl processing of attacker input. The project was informed of the problem early through an issue report but has not responded yet.

CVE-2026-40519 High · 7.5 CWE-78 Jun 8, 2026

Nginx Proxy Manager Authenticated RCE via setupCertbotPlugins()

Nginx Proxy Manager versions 2.9.14 through 2.15.1, fixed in commit a5db5ed, contain an authenticated remote code execution vulnerability via OS command injection in the setupCertbotPlugins() function in backend/setup.js, allowing attackers with certificates:manage permission to execute arbitrary commands by storing a malicious payload in the dns_provider_credentials field. The user-controlled dns_provider_credentials value is interpolated directly into a shell command executed via child_process.exec() without sanitization or escaping, causing the injected command to execute upon backend restart.
