The Styler for Ninja Forms plugin for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the deactivate_license function in all versions up to, and including, 3.3.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary option values on the WordPress site. This can be leveraged to delete an option that would create an error on the site and deny service to legitimate users. Note: This issue can also be used to add arbitrary options with an empty value.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.

Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user’s privileges and any permissions or other access-control specifications that apply to the resource. When access control checks are not applied, users are able to access data or perform actions that they should not be allowed to perform. This can lead to a wide range of problems, including information exposures, denial of service, and arbitrary code execution.
