CF7 Apps - Security Vulnerability (CVE-2026-120547)

Q: Am I affected by this vulnerability?

You are affected if your site runs CF7 Apps.

Q: How do I fix it?

Update CF7 Apps to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Unauthorised administrator detection in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Privilege Escalation flaw. An attacker who exploits it can raise a low-privilege account, or none at all, to administrator.

Vulnerability CVE-2026-120547 PLUGIN cf7-apps MEDIUM

The CF7 Apps – Honeypot, Database, Redirection, Webhook, and Addons for Contact Form 7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpcf7-form (CF7 form body; the [honeypot ...] tag value)' parameter in all versions up to, and including, 3.8.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is only a meaningful privilege escalation on multisite installations or those with DISALLOW_UNFILTERED_HTML enabled, as Editor-level users on default single-site installs already possess the unfiltered_html capability.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update CF7 Apps to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Unauthorised administrator detection in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Alert when a new administrator appears or a role is escalated. Creating a hidden admin is the most common persistence step after a WordPress compromise.
