Description
The Ninja Forms - Save Progress plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.0.30. This is due to the lack of capability checks and nonce verification in the 'bulk_actions' function. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary database records from the 'wp_nf3_objects' table, such as saved submissions.
