CVE-2026-42220
Nginx-UI: Authenticated settings disclosure exposes node.secret and enables trusted-node authentication abuse, backup exfiltration, and restore-based nginx-ui state rollback
Impact
Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, an authenticated user can call GET /api/settings and retrieve sensitive configuration values, including node.secret. The same node.secret is accepted by AuthRequired() through the X-Node-Secret header (or node_secret query parameter), causing the request to be treated as authenticated via the trusted-node path and associated with the init user. This issue has been patched in version 2.3.8.
