SCA: security update for github.com/0xJacky/nginx-ui (GHSA-q4w7-56hr-83rm)

medium Tenable Self-Hosted Container Security Plugin ID 441279

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 version 2.3.8, the GetSettings API
 handler (api/settings/settings.go:24-65) serializes all settings structs to JSON and returns them to
 authenticated users. Many sensitive fields are tagged with protected:"true" - however, this tag is only
 enforced during writes (via ProtectedFill in SaveSettings) and is completely ignored during reads. This
 exposes 40+ protected fields including JwtSecret (enabling auth token forgery), NodeSecret (enabling
 cluster node impersonation), OIDC ClientSecret (enabling OAuth account takeover), and the IP whitelist
 configuration. This issue has been patched in version 2.3.8. (CVE-2026-42223)

Solution

Update the github.com/0xJacky/nginx-ui library and its related packages to version 2.3.8 or later.
