Executive Summary

The User Access Manager WordPress plugin before version 2.3.15 has a flaw where access restrictions set on posts, pages, or custom post types are not enforced for REST API requests. This allows unauthenticated attackers to bypass restrictions and read content meant only for specific user groups.

Detection Guidance

Check the installed version of the User Access Manager plugin. If it is below 2.3.15, the system is vulnerable. Use commands like 'wp plugin list' in WordPress or inspect the plugin files for version details.

Impact Analysis

Unauthenticated attackers could access sensitive or private content restricted by the plugin. This includes posts, pages, or custom post types that were intended to be visible only to certain users, potentially exposing confidential information.

Compliance Impact

This vulnerability could lead to unauthorized access to protected data, violating compliance requirements for data protection such as GDPR or HIPAA. Exposure of restricted content may result in legal penalties or loss of certification.

Mitigation Strategies

Update the User Access Manager plugin to version 2.3.15 or later immediately. If updating is not possible, consider disabling the plugin temporarily until an update is applied.
