CVE-2026-84315 Details
Description
Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, Nginx UI does not apply RequireSecureSession to multiple authenticated mutation routes even though OTP-enabled users are expected to present a fresh X-Secure-Session-ID for sensitive actions. A stolen authenticated session can therefore create or alter automatic backups, DNS credentials and records, certificates and ACME users, Nginx control settings, and site or stream automation without completing the OTP or passkey step-up. This issue is fixed in version 2.4.1.
A vulnerability exists in Nginx UI versions prior to 2.4.1, where the application fails to enforce the 'RequireSecureSession' middleware on several authenticated mutation routes. This oversight allows attackers with stolen authenticated sessions to bypass one-time password (OTP) requirements and perform sensitive actions, such as modifying DNS credentials, managing automatic backups, and altering Nginx control settings. The issue arises because OTP-enabled users are expected to provide a fresh 'X-Secure-Session-ID' for critical operations, but this requirement is not consistently applied.
Users can update to Nginx UI version 2.4.1 or later, where this vulnerability has been addressed.
