CVE-2026-107809: Cross-Site Request Forgery (CSRF)

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, AuthRequired accepts a browser-managed token cookie as an API credential after the front end stores the JWT in that cookie. Because management endpoints do not universally require a CSRF token or perform Origin or...

CVE-2026-107812: Download of Code Without Integrity Check

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, the self-upgrade mechanism validates a downloaded binary only with a same-origin digest obtained from the same upgrade mirror. A compromised mirror or network attacker able to alter both responses can supply a...

CVE-2026-107811: Exposure of Sensitive Information to an Unauthorized Actor

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,...
