Technical details
A response-disclosing server-side request forgery (SSRF) in the POST /api/templates/compose endpoint allows authenticated users to supply attacker-controlled repository URL and stackfile values that are concatenated and fetched by the server without validation of scheme, hostname, IP range, localhost, metadata addresses, or redirects. The fetched response body is returned directly to the attacker in the JSON response, enabling disclosure of internal HTTP services, cloud metadata endpoints, and credentials accessible from the server's network position.
