Unauthenticated SSRF via arbitrary ping URL
Published Feb 6, 2026 · Updated Feb 6, 2026
SSRF in Homarr before 1.52.0 allows remote attackers to make server-side HTTP requests and probe network services through a public endpoint. The widget.app.ping tRPC procedure accepts any URL, passes it to sendPingRequestAsync, and returns status, error, and timing differences without destination validation. Any network user who can reach Homarr needs no account and can distinguish reachable services or contact internal HTTP endpoints from the server's network context.
