What is CVE-2026-107813?
CVE-2026-107813 is a high-severity missing authorization vulnerability in 0xJacky nginx-ui, published on 9 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, the api/cluster router exposes node and namespace mutation operations and cluster-wide Nginx reload or restart operations with AuthRequired but without RequireSecureSession. An authenticated OTP-enabled user possessing a stolen or persisted JWT can therefore perform node CRUD, read or replace node credentials, change namespaces, and invoke nodes/reload_nginx or nodes/restart_nginx without a fresh second-factor step-up. This issue is an incomplete fix for CVE-2026-84315 and is fixed in version 2.5.0.
Weakness: CWE-862
