Advanced Contact form 7 DB <= 2.1.3 - Missing Authorization to Authenticated (Custom+) Unauthorized Data Import via 'import_cf7_id'

Description

The Advanced Contact form 7 DB plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with custom-level access and above, to import forged CSV submission records into any Contact Form 7 form managed by the plugin.
