    Omnom through 0.9.0 SSRF via Add Feed /add_feed Route
    Summary
    Omnom through 0.9.0 contains a server-side request forgery vulnerability that allows authenticated users to make server requests to arbitrary hosts by submitting feed URLs to /add_feed. Attackers can supply internal addresses that getFeedInfo, gofeed ParseURL, and fetchImageAsInlineURL fetch without validation, using reflected error messages to probe internal hosts and ports.
