Name of the Vulnerable Software and Affected Versions Duplicate Post Page Menu & Custom Post Type plugin for WordPress versions up to, and including, 2.3.1

Description The issue is related to unauthorized page and post duplication due to a missing capability check on the duplicate ppmc post as draft function. This allows authenticated attackers with subscriber access or higher to duplicate posts and pages.

Recommendations For versions up to, and including, 2.3.1, update to a version higher than 2.3.1 to resolve the issue. As a temporary workaround, consider disabling the duplicate ppmc post as draft function until a patch is available. Restrict access to the plugin's functionality to minimize the risk of exploitation. Avoid using the plugin's post and page duplication features until the issue is resolved.
