## Description

The Zoho CRM Lead Magnet plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via submitted form field values in all versions up to, and including, 1.8.2.3, due to insufficient output escaping. When the [zohocrm-web-form] form is shown again after a validation error, submitted values are placed into single-quoted HTML value attributes after only sanitize_text_field(), which does not encode quotes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can trick a user into submitting a crafted form request, for example by visiting a malicious page that auto-submits the form.
