CVE-2023-35914Network attack vector

Unauthenticated guest-order disclosure via user-controlled key

Published Dec 20, 2023 · Updated Apr 28, 2026

IDOR in WooCommerce Subscriptions 5.1.2 and earlier allows remote attackers to read limited data about unpaid guest orders. Neither the CNA nor WooCommerce identifies the request handler, parameter, or failed ownership check; the vendor only describes a user-controlled key and access to limited, non-payment-related information. No account or user interaction is required, and the published impact is limited to confidentiality.
