CVE-2026-110023 · Severity: medium · CVSS 5.9 · Published 2026-10-31

WP Data Access is a WordPress plugin that allows administrators to create interactive apps with tables, forms, dashboards, and charts connected to databases. An unauthenticated attacker can extract sensitive data from any published app's database—including WordPress user password hashes, email addresses, and password-reset keys—when the app is configured with anonymous REST API access, which is the default for publicly embedded apps.

## Technical details

The vulnerability exists in the WPDA_Apps.php REST API handler, where the 'rel_tab' parameter is not properly validated, allowing unauthenticated attackers to access database contents. An attacker can craft malicious requests to extract rows and columns from any database table backing a published app when REST API authorization is set to 'anonymous' (the default configuration). This requires only that an administrator has published at least one app with anonymous REST API access enabled.
