Quick assessment

Affected
0xJacky nginx-ui
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Nginx UI 是 Nginx Web 服务器的图形化管理界面。在版本 2.0.0 至 2.5.0 之间， 路由暴露了节点和命名空间的修改操作，以及针对集群范围的 Nginx 重载或重启操作，这些操作虽要求身份认证（AuthRequired），但未强制要求安全的会话验证（RequireSecureSession）。因此，持有被盗或持久化 JWT 令牌且启用了一次性密码（OTP）认证的用户，可以在未经二次增强认证（step-up）的情况下，执行节点的增删改查（CRUD）操作、读取或替换节点凭证、更改命名空间，并调用

Vulnerability Title
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
Source: CVE Program / CVE List V5
Vulnerability Description
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.
