Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the API Request component, which accepts user-supplied URLs and issues HTTP requests from the server without adequate filtering of internal or private network addresses. An attacker can access internal resources and retrieve sensitive information by supplying crafted URLs to endpoints that execute flows with an API key.
