CVE-2026-107811

HIGH 8.8

Published 2026-10-09 · Last modified 2026-10-14

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, ordinary authenticated users can access /api/nodes and /api/nodes/:id, whose responses serialize the node token field. The same token is accepted as X-Node-Secret by AuthRequired and maps the request to initUser, allowing the user to impersonate a trusted node against a reachable cluster member. This cross-node authentication bypass can expose sensitive management operations, including configuration synchronization and service restart. This issue is fixed in version 2.5.0.
