The WP Data Access plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.5.68 via the 'checkappaccess' function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to access data from protected app containers by exploiting a mismatch between the authorization check (performed against appid) and data retrieval (performed using cntid without verifying container ownership).

The WP Data Access plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.3.7. This is due to a lack of authorization checks on the multiplerolesupdate function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'wpdarole[]' parameter during a profile update. This requires the 'Enable role management' setting to be enabled for the site.

The WP Data Access WordPress plugin before 5.0.0 does not properly sanitise and escape the backupdate parameter before using it a SQL statement, leading to a SQL injection issue and could allow arbitrary table deletion
