Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Nginx-UI (Go module github.com/0xJacky/Nginx-UI) versions up to and including 2.3.4 are vulnerable to server-side request forgery through its cluster proxy middleware. An authenticated user can create a cluster node pointing to an arbitrary internal URL and then route API requests through it, so the server sends requests to internal services such as localhost or cloud metadata endpoints. No fixed version is listed.
