CVE-2026-10662Public exploitNetwork attack vector

Internal service access via unchecked ZIP URL

Published Jun 2, 2026 · Updated Jun 2, 2026

Server-side request forgery in Blender MCP allows remote authenticated users to reach internal HTTP services through a crafted ZIP URL. The import_generated_asset_hunyuan flow passes zip_file_url to the add-on, which accepts any HTTP(S) destination and calls requests.get without restricting resolved addresses. Hunyuan3D must be enabled and the MCP server running; the Blender process can then issue GET requests to internal, loopback, or link-local endpoints.
