AI-suggested

Since the vulnerability requires authentication, restricting user privileges and monitoring feed URL inputs may reduce risk. Users should check the vendor advisory for updates or patches.

Description

Omnom versions through 0.9.0 have a server-side request forgery (SSRF) vulnerability that allows authenticated users to make server requests to arbitrary hosts by submitting feed URLs to the /add_feed endpoint. This flaw enables attackers to supply internal addresses that the application fetches without validation, potentially allowing probing of internal hosts and ports via reflected error messages.
