Detailsinfo

A vulnerability classified as problematic was found in udamadu Inquiry Form to Posts or pages Plugin up to 1.0 on WordPress. This vulnerability affects the function check_admin_referer. The manipulation of the argument inq_hidden with an unknown input leads to a cross-site request forgery vulnerability. The CWE definition for the vulnerability is CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. As an impact it is known to affect integrity. CVE summarizes:

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.

The weakness was published by Muhammad Nur Ibnu Hubab. The advisory is available at wordfence.com. This vulnerability was named CVE-2026-6293 since 04/14/2026. The exploitation appears to be easy.
