Craft CMS versions 3.5.0-4.16.17 and 5.0.0-RC1-5.8.21 contain a server-side request forgery vulnerability in the save_images_Asset GraphQL mutation that allows authenticated users to bypass hostname validation and retrieve internal URLs by specifying domains resolving to private IP addresses. By uploading files with non-image extensions like .txt, attackers can bypass downstream validation to access sensitive data including AWS instance metadata credentials from the host system. Public exploit code exists for this vulnerability, though patches are available in versions 4.16.18 and 5.8.22.
