Overview
Affected versions of this package are vulnerable to Missing Authorization via the GET /api/badge/:id/ping/:duration? endpoint, which fails to verify if the requested monitor belongs to a public group. An attacker can access average ping and response time data for private monitors by sending unauthenticated requests to this endpoint, potentially allowing them to enumerate private monitor IDs and infer the existence and reachability of internal services.
