The Kadence WooCommerce Email Designer plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the customer name input is not properly sanitized or escaped, enabling unauthenticated attackers to inject malicious scripts that execute in the context of users viewing the injected content. This affects all plugin versions up to 1.5.17. The vulnerability has a CVSS 3.1 base score of 7.2, indicating a high severity with network attack vector, low attack complexity, no privileges required, no user interaction needed, and impacts confidentiality and integrity with no availability impact. No patch or official fix information is currently provided by the vendor.

Successful exploitation allows an unauthenticated attacker to execute arbitrary JavaScript in the context of users accessing the injected page, potentially leading to information disclosure and integrity compromise of user data. There is no direct impact on availability. The vulnerability affects confidentiality and integrity of data processed or displayed by the plugin.
