漏洞描述
Kan, an open-source project management tool (Trello alternative), versions 0.5.4 and below are vulnerable to an unauthenticated Server-Side Request Forgery in the /api/download/attatchment endpoint. The endpoint passes the attacker-controlled `url` query parameter straight to a server-side fetch() without validating the destination host, allowing an unauthenticated attacker to make the server issue arbitrary outbound HTTP requests and read back the full response body.
