CVE-2026-84312 Nginx UI: Casdoor SSO callback uses a constant `state` parameter (login CSRF)

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, GetCasdoorUri uses the configured Casdoor application name as a constant OAuth state value and CasdoorCallback does not compare the submitted state with a value bound to the initiating browser session. An unauthenticated...

CVE-2026-84312

The Nginx UI web interface for the Nginx web server is vulnerable to a login CSRF attack in versions prior to 2.4.1 . The root cause is that the GetCasdoorUri function uses a constant OAuth state value (the configured Casdoor application name), and the CasdoorCallback function fails to validate t...

CVE-2026-84360

The Nginx UI web interface for the Nginx web server is vulnerable to an authentication bypass in versions prior to 2.4.1 . The root cause is that while HTTP configuration mutation routes require RequireSecureSession , the /mcp and /mcp_message endpoints only require ordinary authentication. This ...

CVE-2026-84360 Nginx UI: OTP secure-session step-up can be bypassed via MCP configuration tools

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, the HTTP configuration mutation routes require RequireSecureSession, but /mcp and /mcpmessage require only ordinary authentication before exposing nginxconfigadd and nginxconfigmodify. An OTP-enabled user with a normal JWT...

CVE-2026-84316

The Nginx UI web user interface (versions prior to 2.4.1 ) is vulnerable to a validation bypass in the config.ValidateConfigDirectives function. The software incorrectly splits configuration by newline and only validates the first token, allowing an authenticated caller to append restricted direc...

CVE-2026-84316 Nginx UI: nginx config directive denylist (ValidateConfigFile) is bypassable via same-line ";" separation → authenticated directive injection (RCE on the official image)

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, config.ValidateConfigDirectives splits configuration by newline and checks only the first directive token on each line even though Nginx permits multiple semicolon-separated directives on one line. An authenticated caller...

CVE-2026-84319

The Nginx UI web interface for the Nginx web server is vulnerable to a protection mechanism failure in versions prior to 2.4.1 . While the regular HTTP configuration API correctly rejects restricted directives like load_module, js_import, and js_content, the MCP configuration interface fails to d...

CVE-2026-84319 Nginx UI: MCP configuration tools bypass restricted directive validation and allow secondary authenticated users to execute NJS in Nginx worker context

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, the regular HTTP configuration API rejects restricted Nginx directives such as loadmodule, jsimport, and jscontent. However, the MCP configuration interface allows a secondary authenticated user to write and apply equivale...

CVE-2026-84317

Prior to version 2.4.1 , Nginx UI (a web user interface for the Nginx web server) contains a vulnerability where the mcp/config/config_add.go path (MCP tool nginx_config_add) fails to call the internal/config/validation.go security control. While other config-write paths block dangerous directive...

CVE-2026-84317 Nginx UI: MCP nginx_config_add skips config directive validation → authenticated nginx directive injection (RCE on the official image)

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, internal/config/validation.go ValidateConfigFile is a security control that blocks dangerous nginx directives — js, perl, loadmodule of the njs/perl modules, and user root. It is enforced on three of the four config-write...

CVE-2026-84313 Nginx UI: TOTP / passkey enrolment requires no re-authentication, enabling persistent account takeover

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, POST /api/otpenroll and POST /api/finishpasskeyregister are registered outside RequireSecureSession and accept a normal authenticated session without verifying the current password. An attacker with a stolen JWT can bind a...

CVE-2026-84313

The Nginx UI web interface (prior to version 2.4.1 ) is vulnerable to unauthorized account persistence because the POST /api/otp_enroll and POST /api/finish_passkey_register endpoints are registered outside of RequireSecureSession . These endpoints accept a standard authenticated session without ...

CVE-2026-84321 Nginx UI: Standalone short tokens survive administrative revocation in cache and authenticate again after account re-enable

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, GenerateShortToken creates standalone short-token records without a long Token value, but DeleteUserTokens invalidates cached entries only when the long Token field is nonempty. A revoked short token can therefore remain i...
