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).
AnalysisAI
Insecure Direct Object Reference in WP Data Access plugin for WordPress (all versions through 5.5.68) exposes protected app container data to unauthenticated attackers via the check_app_access function. The flaw stems from a logical mismatch: authorization is validated against the app_id parameter, but the subsequent data retrieval uses cnt_id without verifying that the requested container actually belongs to the authorized app - allowing a user to pass an authorized app_id to clear the access gate while supplying an arbitrary cnt_id to reach a different container's data. …
