CVE-2026-107811
0xJacky/nginx-ui /api/nodes Leaks Cluster Node Tokens and Allows Cross-Node Impersonation as initUser
Description
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.
