Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. Prior to version 2.0.13, fallbackToFrontend in the dashboard's NoRoute handler treats any URL whose raw string starts with /dashboard as an admin-frontend asset request. The check uses strings.HasPrefix, not a path-segment match, so the input /dashboard../data/config.yaml is accepted; strings.TrimPrefix leaves ../data/config.yaml; and path.Join("admin-dist", "../data/config.yaml") normalizes to data/config.yaml — which os.Stat finds and http.ServeFile returns. No authentication required. This issue has been patched in version 2.0.13.

Affected: Go: github.com/nezhahq/nezha

### Summary `fallbackToFrontend` in the dashboard's `NoRoute` handler treats any URL whose **raw string** starts with `/dashboard` as an admin-frontend asset request. The check uses `strings.HasPrefix`, not a path-segment match, so the input `/dashboard../data/config.yaml` is accepted; `strings.TrimPrefix` leaves `../data/config.yaml`; and `path.Join("admin-dist", "../data/config.yaml")` normalizes to `data/config.yaml` — which `os.Stat` finds and `http.ServeFile` returns. No authentication required. In default deployments (the values shipped in `model/config.go` and the layout shipped in the project `Dockerfile`) `data/config.yaml` contains the HS256 `jwt_secret_key` used by `cmd/dashboard/controller/jwt.go` to sign every dashboard session cookie. A unauth attacker reads that secret, forges an admin JWT, and signs in as any user — full dashboard takeover from one GET request.
