WooCommerce Subscriptions plugin for WordPress is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the class-wcs-admin-post-types.php script. A remote attacker could exploit this vulnerability using the WCS_Admin_Post_Types parameter to inject malicious script into a Web page which would be executed in a victim’s Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.
