Lifecycle Timeline
2Description
Homarr is an open-source dashboard. Prior to 1.52.0, a public (unauthenticated) tRPC endpoint widget.app.ping accepts an arbitrary url and performs a server-side request to that URL. This allows an unauthenticated attacker to trigger outbound HTTP requests from the Homarr server, enabling SSRF behavior and a reliable port-scanning primitive (open vs closed ports can be inferred from statusCode vs fetch failed and timing). This vulnerability is fixed in 1.52.0.
Analysis
Homarr versions prior to 1.52.0 contain an unauthenticated SSRF vulnerability in the widget.app.ping endpoint that accepts arbitrary URLs and performs server-side requests, allowing remote attackers to scan ports and probe internal networks without authentication. The vulnerability enables attackers to infer open versus closed ports through HTTP status codes and response timing, establishing a reliable reconnaissance primitive. …
