CVE-2026-18032 WP Data Access CVE debrief

Who should care

WP Data Access plugin users, WordPress administrators, security teams, and operators of affected systems should be aware of this vulnerability. They should verify their plugin version, assess their database exposure, and implement necessary mitigations to prevent unauthorized access to sensitive information.

Technical summary

The WP Data Access WordPress plugin before 5.5.79 does not validate column names on an unauthenticated AJAX action, allowing arbitrary database column reads, including user password hashes. This could lead to unauthorized access to sensitive information. Affected users should verify their plugin version and take steps to protect their database. The vulnerability has a low defensive priority, and users should review compensating controls for exposed systems while remediation is scheduled and verified.
