CVE-2026-42220

6.5 medium SSVC exploitation: poc Analyzed
NVD · CVE.org

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.
