Guest-order disclosure and manipulation via missing ownership checks
Published Aug 26, 2026 · Updated Aug 26, 2026
Improper access control in Return Refund and Exchange For WooCommerce before 4.6.4 allows remote attackers to alter guest orders via AJAX. Unauthenticated AJAX actions fail to verify that the requester owns the targeted guest order before reading messages, accepting message and attachment posts, or canceling returns. Any reachable store with a guest order is exposed to private-message disclosure and customer impersonation without an account.
