Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Inquiry Form to Posts or Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Form Header' field in versions up to and including 1.0. This is due to insufficient input sanitization when saving via update_option() and lack of output escaping when displaying the stored value. The vulnerability exists in two locations: (1) the plugin settings page at inq_form.php line 180 where the value is echoed into an HTML attribute without esc_attr(), and (2) the front-end shortcode output at inquery_form_to_posts_or_pages.php line 139 where the value is output in HTML content without esc_html(). This makes it possible for authenticated attackers with administrator-level access to inject arbitrary web scripts that will execute whenever a user accesses the plugin settings page or views a page containing the [inquiry_form] shortcode.
