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.
