      "value": "Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 1.17.3, the /api/templates/fetch endpoint accepts a caller-supplied url parameter and performs a server-side HTTP GET request to that URL without authentication and without URL scheme or host validation. The server's response is returned directly to the caller. type. This constitutes an unauthenticated SSRF vulnerability affecting any publicly reachable Arcane instance. This vulnerability is fixed in 1.17.3."

Anterior a la 1.17.3, el endpoint /API/templates/fetch acepta un parámetro url proporcionado por el llamador y realiza una solicitud HTTP GET del lado del servidor a esa URL sin autenticación y sin validación de esquema de URL o de host. La respuesta del servidor se devuelve directamente al llamador. tipo. Esto constituye una vulnerabilidad SSRF no autenticada que afecta a cualquier instancia de Arcane accesible públicamente. Esta vulnerabilidad se corrige en la 1.17.3."
