Subscriber-level order disclosure via improper capability check
Published Apr 14, 2026 · Updated Apr 14, 2026
Missing authorization in Arraytics Eventin 4.1.8 and earlier allows remote authenticated users to read arbitrary customer order data. The get_item_permissions_check() REST authorization handler accepts Subscriber-level requests without verifying permission for the requested order, so sequential order IDs expose names, email addresses, and phone numbers. Any WordPress account with Subscriber-level access can enumerate orders; the reported impact is limited to disclosure, with no modification or service interruption.
