CVE-2023-7320Network attack vectorHinoki check available

Unauthenticated PII disclosure via permissive Store API CORS

Published Oct 29, 2025 · Updated Oct 29, 2025

Information exposure in Automattic WooCommerce 7.8.2 and earlier allows remote attackers to read customer PII through Store API requests. Affected Store API code leaves WordPress's default REST CORS handler enabled, which reflects arbitrary Origin values while permitting credentials on PII-bearing responses. No WooCommerce account or API key is required; exposure is limited to affected API responses, with no reported write or availability impact.
