Pico through 4.1.2 SSRF in Feeds Service via run SSH Command

Pico through 4.1.2 contains a server-side request forgery vulnerability in the feeds service that allows signed-up users to make the server fetch arbitrary URLs via the run SSH command. Attackers can upload a feeds digest post listing internal URLs and trigger immediate fetching through Fetcher.ParseURL to reach loopback, RFC1918, and cloud metadata endpoints.
