A flaw was found in omnom. An authenticated remote attacker can exploit this flaw by submitting internal addresses to the feed addition endpoint without proper validation. This causes a Server-Side Request Forgery (SSRF), allowing the attacker to make arbitrary network requests from the server and probe internal hosts and ports using reflected error messages.

Description OSIDB Bzimport 2026-11-10 19:27:19 UTC 
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.
