Authenticated internal-service access via unrestricted image URL imports

Published May 5, 2026 · Updated May 5, 2026

Server-side request forgery in Jegstudio Gutenverse 3.5.3 and earlier allows remote authenticated users to access internal services. The import_images() function uses the attacker-controlled imageUrl value to initiate a server-side request without restricting its destination. Contributor-level access is required; successful requests can query or modify network-restricted internal services.
