Subscriber-level data access and modification via AJAX
Published Oct 20, 2023 · Updated Apr 8, 2026
Improper authorization in Radykal Fancy Product Designer 4.6.9 and earlier allows remote authenticated users to access or modify data. Multiple AJAX handlers accept subscriber requests without checking the capabilities required for the requested administrative operation. Subscriber-level access is sufficient to retrieve unrelated order information or create, update, and delete products, orders, settings, and other sensitive records.
