# Nginx UI: Incomplete fix of CVE-2026-84315 - the api/cluster router was not - wrapped in RequireSecureSession, so those sensitive mutations run without OTP step-up in github.com/0xJacky/Nginx-UI

Nginx UI, a web interface for managing Nginx, leaves its cluster API routes without the OTP step-up check that protects other sensitive actions. An attacker holding a stolen or persisted login token can add, change or delete cluster nodes, read or replace node credentials, and reload or restart Nginx on nodes without a second factor.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- go:github.com/0xJacky/Nginx-UI affected >= 1.9.10-0.20250517140552-daee3ac7ade1, < 1.9.10-0.20260728074433-a3999bd78a3b fixed 1.9.10-0.20260728074433-a3999bd78a3b

## How to check

Check the Go module version of github.com/0xJacky/Nginx-UI in go.mod or the running binary; affected range is up to but not including 1.9.10-0.20260728074433-a3999bd78a3b.

## Fix

Upgrade github.com/0xJacky/Nginx-UI to 1.9.10-0.20260728074433-a3999bd78a3b or later (the description says the fix is in 2.5.0).
Rotate JWTs and node credentials if the instance was exposed while vulnerable.

## From the sources

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, the api/cluster router exposes node and namespace mutation operations and cluster-wide Nginx reload or restart operations with AuthRequired but without RequireSecureSession. An authenticated OTP-enabled user possessing a stolen or persisted JWT can therefore perform node CRUD, read or replace node credentials, change namespaces, and invoke nodes/reload_nginx or nodes/restart_nginx without a fresh second-factor step-up. This issue is an incomplete fix for CVE-2026-84315 and is fixed in version 2.5.0.
