Source record

Technical description

The Inquiry Form to Posts or Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery leading to Stored Cross-Site Scripting in version 1.0. This is due to missing nonce validation on the plugin settings update handler, combined with insufficient input sanitization on all user-supplied fields and missing output escaping when rendering stored values. The settings handler fires solely on the presence of `$_POST['inq_hidden'] == 'Y'` with no call to `check_admin_referer()` and no WordPress nonce anywhere in the form or handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts via a forged request that tricks a logged-in Administrator into visiting a malicious page.

CVE / CNA vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
