ClaraVerse through 0.3.1 contains server-side request forgery protection bypasses in the download_file and scrape_web agent tools. Authenticated users can bypass hostname validation and IPv6 transition address filtering to make the server request internal services and cloud instance metadata endpoints.
Weakness
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
