Technical details

The vulnerability is classified as a Missing Authorization (CWE-862) issue within the 'vsz_cf7_export_to_excel' function of the Advanced Contact form 7 DB plugin. Because the plugin fails to perform a capability check (such as current_user_can()) on this specific function, any authenticated user, including those with the lowest 'Subscriber' permissions, can trigger the export process. An attacker can exploit this by sending a crafted request to the server to download an Excel file containing all stored form submissions. The issue affects all versions of the plugin up to and including 2.0.9. A patch has been identified in subsequent changesets.
