The Mapster WP Maps plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to an insufficient capability check on the mapster_wp_maps_set_option_from_js() function in all versions up to, and including, 1.5.0. This makes it possible for authenticated attackers, with contributor-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
The product does not perform or incorrectly performs 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 consistently - or not at all - 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.
