Homarr · Homarr · CVE-2026-25123
**Name of the Vulnerable Software and Affected Versions**
Homarr versions prior to 1.52.0
**Description**
Homarr is an open-source dashboard susceptible to Server-Side Request Forgery (SSRF). A public, unauthenticated tRPC endpoint, `widget.app.ping`, accepts an arbitrary URL and makes a server-side request to that URL. This allows an unauthenticated attacker to initiate outbound HTTP requests from the Homarr server. This capability can be used for SSRF and as a reliable port-scanning primitive, where the status of ports can be determined by analyzing status codes and request timing. The vulnerable API endpoint is `widget.app.ping`. The `url` parameter is used to specify the target URL for the server-side request.
**Recommendations**
Update to version 1.52.0 or later.
