## Description

The Form Maker by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Show on Map' link in the admin submissions table in all versions up to, and including, 1.15.50, due to insufficient input validation and output escaping. Submitted map coordinate text is added to an admin-ajax link without URL encoding, so a submitter can add extra query parameters, including a different action, to a link that already carries the administrator's valid nonce. The 'field_id' parameter of the country list popup is then echoed unescaped inside a JavaScript string. This makes it possible for unauthenticated attackers who submit a form to inject arbitrary web scripts that execute when an administrator clicks the 'Show on Map' link for that submission.
