Publication date: 2026-08-09

Last updated on: 2026-08-09

Assigner: WPScan

Description
The WP Data Access WordPress plugin before 5.5.79 does not validate the column names it accepts on one of its unauthenticated AJAX actions, and the nonce guarding that action does not cover them, allowing unauthenticated attackers to read arbitrary columns of the database table the affected front-end form is bound to, including user password hashes where that table is the users table.

Executive Summary

CVE-2026-18032 is a vulnerability in the WP Data Access WordPress plugin before version 5.5.79. It allows unauthenticated attackers to read arbitrary columns from a database table linked to an affected front-end form by exploiting improper validation of column names in an unauthenticated AJAX action. The nonce protecting this action does not cover the column names, enabling unauthorized access.

Detection Guidance

Check the installed version of the WP Data Access plugin. If it is below 5.5.79, the system is vulnerable. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files directly.

Impact Analysis

This vulnerability allows attackers to access sensitive data, including user password hashes if the affected table is the WordPress users table. Unauthenticated attackers can read arbitrary columns from the database, potentially exposing confidential information.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized access to sensitive data such as user password hashes. Exposure of such data violates privacy and security requirements mandated by these regulations.

Mitigation Strategies

Update the WP Data Access plugin to version 5.5.79 or later immediately. Remove or disable the plugin if an update is not possible. Monitor for unauthorized access or data exfiltration.
