Name of the Vulnerable Software and Affected Versions: Rendertron versions prior to 3.0.0

Description: The issue allows an attacker to perform a Server-Side Request Forgery (SSRF) attack by using a specially crafted webpage to force a rendertron headless chrome process to render internal sites it has access to, and display it as a screenshot.

Recommendations: For Rendertron versions prior to 3.0.0, upgrade to version 3.0.0 to resolve the issue. If an upgrade to version 3.0.0 is not possible, secure the infrastructure to limit the headless chrome's access to your internal domain.
