The Anonymous Restricted Content plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.6.5 via the WordPress core search feature. This makes it possible for unauthenticated attackers to extract sensitive data from posts that have been restricted to logged-in users.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
During installation, installed file permissions are set to allow anyone to modify those files.
