CVE-2022-2099Public exploitNetwork attack vector

Stored HTML injection via unescaped gateway titles

Published Jul 17, 2022 · Updated Aug 3, 2024

Stored HTML injection in WooCommerce before 6.6.0 allows remote authenticated users to alter checkout content through payment titles. The payment-gateway settings path stores administrator-supplied title markup without sufficient sanitization, and checkout and admin views render that stored value as HTML. Administrator privileges are required to change a gateway title, and the injected markup is displayed to both administrators and storefront visitors.
