A vulnerability was found in ContentStudio Plugin up to 1.2.5 on WordPress (WordPress Plugin). It has been rated as critical. Affected by this issue is the function cstu_get_metadata. The manipulation with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-862.

The ContentStudio plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several functions in versions up to, and including, 1.2.5. This makes it possible for unauthenticated attackers to obtain the blog metadata (via the function cstu_get_metadata) that includes the plugin's contentstudio_token.
