 "title": "WS Form LITE <= 1.12.18 - Unauthenticated Stored Cross-Site Scripting via Nested Form Field Values",
 "description": "The WS Form LITE plugin for WordPress is vulnerable to Stored Cross-Site Scripting via submitted form field values in all versions up to, and including, 1.12.18. This is due to insufficient input sanitization and output escaping: nested arrays or objects posted as field values were stored as-is, and the client-side esc_html function returned non-string values without encoding them. This makes it possible for unauthenticated attackers to submit a form with crafted nested values and inject arbitrary web scripts that execute when a user, such as an administrator viewing form submissions, accesses a page rendering those values.",
