CVE-2026-65317
Verba (goldenverba) Server-Side Request Forgery via /api/connect and Same-Origin Middleware Bypass
Description
Verba RAG application version 2.1.3 contains a server-side request forgery vulnerability combined with a same-origin middleware bypass that allows unauthenticated remote attackers to make the server issue arbitrary HTTP requests by supplying a crafted Origin header and attacker-controlled host and port values. Attackers can bypass the localhost origin check in the API middleware by sending any Origin value prefixed with ' regardless of port, then submit arbitrary host and port parameters to the /api/connect endpoint to cause the server to issue outbound GET requests to attacker-controlled infrastructure.

Action Type Old Value New Value Added Translation Title: Verba de Weaviate, Description: La aplicación Verba RAG versión 2.1.3 contiene una vulnerabilidad de falsificación de petición del lado del servidor combinada con un bypass de middleware de mismo origen que permite a atacantes remotos no autenticados hacer que el servidor emita peticiones HTTP arbitrarias al proporcionar una cabecera Origin manipulada y valores de host y puerto controlados por el atacante. Los atacantes pueden omitir la verificación de origen de localhost en el middleware de la API enviando cualquier valor de Origin prefijado con ’ independientemente del puerto, luego enviar parámetros de host y puerto arbitrarios al endpoint /api/connect para hacer que el servidor emita peticiones GET salientes a infraestructura controlada por el atacante. -
