CVE-2026-27797Public exploitNetwork attack vector

Unauthenticated SSRF via unrestricted RSS feed URLs

Published Mar 7, 2026 · Updated Mar 7, 2026

SSRF in Homarr before 1.54.0 allows remote attackers to make outbound HTTP requests through the public RSS feed query. The widget.rssFeed.getFeeds publicProcedure forwards each caller-controlled URL to @extractus/feed-extractor without blocking loopback, private, or reserved destinations. No authentication or user interaction is required, and successful requests expose internal HTTP services reachable from the Homarr host or container network context.
