CVE-2026-22681

OpenViking before 0.3.4 contains a server-side request forgery vulnerability that allows authenticated low-privilege attackers to access internal network services by submitting arbitrary URLs to the resources API endpoint. Attackers can POST a crafted URL to /api/v1/resources, causing the server to issue outbound HEAD and GET requests with redirects enabled to loopback, RFC 1918, link-local, or cloud metadata addresses, then read back responses through normal content APIs to enumerate and interact with internal services.

Summary		(es) OpenViking anterior a 0.3.4 contiene una vulnerabilidad de falsificación de petición del lado del servidor que permite a atacantes autenticados con bajos privilegios acceder a servicios de red internos al enviar URLs arbitrarias al endpoint de la API de recursos. Los atacantes pueden hacer un POST de una URL manipulada a /api/v1/resources, haciendo que el servidor emita peticiones salientes HEAD y GET con redirecciones habilitadas a direcciones de loopback, RFC 1918, link-local o de metadatos de la nube, para luego leer las respuestas a través de APIs de contenido normales para enumerar e interactuar con servicios internos.
