CVE-2019-18834
Persistent XSS in the WooCommerce Subscriptions plugin before 2.6.3 for WordPress allows remote attackers to execute arbitrary JavaScript because Billing Details are mishandled in WCS_Admin_Post_Types in class-wcs-admin-post-types.php.
Does this matter?
Lower severity and a low EPSS score (1.63%). Track it; it rarely justifies an emergency change on its own.
