User Access Manager < 2.3.15 - Unauthenticated Restricted Content Disclosure via REST API

The User Access Manager WordPress plugin before 2.3.15 does not apply its access restrictions to REST API requests, allowing unauthenticated attackers to read the content of posts, pages and custom post types that have been restricted to specific user groups.

The user-access-manager plugin before 1.2 for WordPress has CSRF.
