What the vulnerability does
01Description
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 'check_app_access' 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 app_id) and data retrieval (performed using cnt_id without verifying container ownership).
Explanation of Vulnerability in Simple Terms
02Summary
WP Data Access versions up to 5.5.68 contain an authorization bypass vulnerability that allows unauthenticated attackers to read sensitive data by manipulating user-controlled keys. The vulnerability does not require user interaction or special network conditions. Site administrators should update to a version newer than 5.5.68 to prevent unauthorized data access.
