CVE-2026-18032: CWE-200 Information Exposure in WP Data Access
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.
AI Analysis
Technical Summary
CVE-2026-18032 is an information exposure vulnerability (CWE-200) in the WP Data Access WordPress plugin versions prior to 5.5.79. The flaw arises because the plugin does not validate column names accepted by one of its unauthenticated AJAX actions. Additionally, the nonce mechanism intended to protect this action does not cover the column name parameter, enabling unauthenticated attackers to read arbitrary columns from the database table bound to the affected front-end form. This can include sensitive data such as user password hashes if the users table is involved.
Potential Impact
An attacker can exploit this vulnerability without authentication to read arbitrary database columns, potentially exposing sensitive information including user password hashes. This could lead to user credential compromise if password hashes are obtained and cracked.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected AJAX action if possible or disable the plugin. Monitor vendor channels for updates and apply any official patches promptly once released.
