Technical details

The JetFormBuilder plugin for WordPress (versions up to 3.6.3) contains a missing authorization check (CWE-862) within its REST API endpoints related to the 'get_from_db' generator function. An unauthenticated attacker can exploit this by sending a crafted request to the generator update endpoint, provided they can identify a valid form ID and field name from the site's public frontend. Successful exploitation allows the attacker to query and retrieve all distinct values for any arbitrary 'wp_postmeta' key, potentially exposing WooCommerce customer PII, attachment paths, and third-party API tokens. A patch is available in versions following 3.6.3.
