Technical details

The Broadstreet plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) vulnerability via the 'get_sponsored_meta' AJAX action. The root cause is a lack of proper validation and authorization checks on a user-controlled key used to retrieve post metadata. An authenticated attacker with Subscriber-level permissions or higher can send crafted AJAX requests to disclose metadata from private posts. This vulnerability is tracked as CWE-639. A patch is available in version 1.53.2, which implements the necessary validation to prevent unauthorized metadata disclosure.
