Technical details
The Broadstreet Ads plugin for WordPress (versions up to and including 1.52.2) suffers from a Broken Access Control vulnerability (CWE-862). The issue stems from a failure to implement proper authorization checks or nonce validation on certain functions. An attacker authenticated with basic 'Subscriber' privileges can exploit this over the network to perform actions that should require higher administrative permissions. This can result in unauthorized modifications to plugin settings or data. The vulnerability is addressed in version 1.53.2.
