CVE-2026-56678
9Router: Kiro region injection allows authenticated SSRF with Authorization header forwarding
Description
9Router is an AI router & token saver. Prior to 0.5.6, the Kiro API-key validation endpoint POST /api/oauth/kiro/api-key builds an upstream URL using a user-controlled region value, allowing an authenticated attacker to supply a crafted region such as kiro-canary.local:8443# and cause 9Router to send the Kiro validation request to an attacker-controlled host while forwarding the submitted Kiro API key as an Authorization header. This issue is fixed in version 0.5.6.

Action Type Old Value New Value Added Translation Title: 9router de decolua, Description: 9Router es un router de IA y ahorrador de tokens. Antes de la versión 0.5.6, el endpoint de validación de clave API de Kiro POST /api/oauth/kiro/api-key construye una URL ascendente utilizando un valor de región controlado por el usuario, permitiendo a un atacante autenticado proporcionar una región manipulada como kiro-canary.local:8443# y hacer que 9Router envíe la solicitud de validación de Kiro a un host controlado por el atacante mientras reenvía la clave API de Kiro enviada como un encabezado de autorización. Este problema está solucionado en la versión 0.5.6. -
