SCA: security update for github.com/0xJacky/Nginx-UI (GHSA-76pm-mq2q-9gcr)

high Tenable Cloud Security Plugin ID 474724

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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_*,
 load_module of the njs/perl modules, and user root. It is enforced on three of the four config-write
 paths: api/config/add.go, api/config/modify.go, and mcp/config/config_modify.go. The fourth path — the MCP
 tool nginx_config_add (mcp/config/config_add.go) — does NOT call it: it writes the caller-supplied content
 straight to disk and reloads nginx. An authenticated MCP caller (or an MCP agent induced via prompt
 injection) can therefore inject exactly the directives the control is meant to block, leading to nginx
 code execution on deployments where the njs/perl module is available (e.g. the official Docker image).
 This issue is fixed in version 2.4.1. (CVE-2026-84317)

Solution

Update the github.com/0xJacky/Nginx-UI library and its related packages to version 1.9.10-0.20260703131214-23d1934099b0 or later.
