CVE-2026-28385

In Canonical LXD versions 4.12 through 6.9, a Server-Side Request Forgery (SSRF) vulnerability in the image import functionality allows authenticated users with the can_create_images entitlement to interact with internal network infrastructure via the /images endpoint. When importing an image from a URL source, the LXD daemon fails to validate or restrict outbound destination IP addresses, allowing connections to loopback, RFC1918 private ranges, and cloud metadata endpoints. This enables error-based port scanning and unauthorized interaction with internal HTTP services from the daemon's network position.

Summary		(es) En las versiones de Canonical LXD 4.12 a 6.9, una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en la funcionalidad de importación de imágenes permite a los usuarios autenticados con el derecho ’can_create_images’ interactuar con la infraestructura de red interna a través del endpoint /images. Al importar una imagen desde una fuente URL, el demonio LXD no valida ni restringe las direcciones IP de destino salientes, permitiendo conexiones a loopback, rangos privados RFC1918 y endpoints de metadatos de la nube. Esto permite el escaneo de puertos basado en errores y la interacción no autorizada con servicios HTTP internos desde la posición de red del demonio.
