CVE-2026-6293Inquiry form to posts or pages <= 1.0 - Cross-Site Request Forgery to Stored Cross-Site Scripting via 'inq_header' Parameter
Medium 4.3
In plain English
A medium-severity cross-site request forgery in Inquiry form to posts or pages from udamadu. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 13% of all known vulnerabilities).
Official 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.
