Name of the Vulnerable Software and Affected Versions RVM WordPress plugin versions prior to 6.4.2

Description The issue concerns a lack of proper authorization, CSRF checks, and validation of the rvm upload regions file path parameter in the rvm import regions AJAX action. This allows any authenticated user to read arbitrary files on the web server.

Recommendations For versions prior to 6.4.2, update to version 6.4.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the rvm import regions AJAX action to minimize the risk of exploitation. Avoid using the rvm upload regions file path parameter in the affected AJAX endpoint until the issue is resolved.
