Joomla Extension - j2commerce.com - Guest checkout address disclosure to any authenticated user (IDOR) in J2Store 1.0.0-3.3.21, 4.0.0-4.0.21, 4.1.0-4.1.6 - `editAddress()` redirected non-owners away only when the loaded address row had a **non-empty** `user_id` belonging to someone else. Guest-checkout address rows have an empty `user_id`, so that check never triggered for them — any logged-in account guessing a small, sequential `address_id` got a guest customer's full name, street address, and phone number rendered prefilled into the edit form.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
