Unauthenticated Data Deletion in Advanced Contact Form 7 - Compact DB Plugin

Publication date: 2026-06-24

Last updated on: 2026-06-24

Assigner: Wordfence

Description
The Advanced Contact Form 7 - Compact DB plugin for WordPress is vulnerable to unauthorized deletion of data due to a missing capability check on the cf7cdb_ajax_delete_user() function in versions up to, and including, 1.0.0. The handler is registered against both `wp_ajax_cf7cdb_delete` and `wp_ajax_nopriv_cf7cdb_delete`, and it performs no nonce verification, no capability check, and no ownership check before invoking `$wpdb->delete()` against the `wp_cf7cdb_data` table with an attacker-supplied integer ID. This makes it possible for unauthenticated attackers to delete arbitrary contact form submission entries stored by the plugin by iterating sequential primary-key IDs.

Executive Summary

The Advanced Contact Form 7 - Compact DB plugin for WordPress has a vulnerability that allows unauthorized deletion of data. This happens because the function cf7cdb_ajax_delete_user() does not check if the user has permission to delete data, does not verify a security nonce, and does not check if the user owns the data before deleting it.

The function is accessible to both authenticated and unauthenticated users via AJAX actions, and it deletes entries from the plugin's data table based on an attacker-supplied ID. This means an attacker can delete arbitrary contact form submission entries by guessing or iterating through the IDs.

Impact Analysis

This vulnerability can lead to the unauthorized deletion of contact form submission data stored by the plugin. An attacker can remove important user-submitted information without any authentication or permission.

The impact is data integrity loss, which could disrupt business operations, cause loss of important user feedback or inquiries, and potentially harm trust in the website.
