JobOps through 0.13.1 SSRF via POST /api/manual-jobs/fetch

JobOps through 0.13.1 contains a server-side request forgery vulnerability in the POST /api/manual-jobs/fetch handler that allows authenticated users, or unauthenticated clients in demo mode, to make the server fetch internal destinations. Attackers can supply loopback, private, or cloud metadata addresses in the url field to read returned page content, disclosing instance metadata and internal service data.
