Executive Summary

The Duplicate Post WordPress plugin before version 1.5.8 has a flaw where it does not check if a user has permission to publish posts when duplicating one. This allows users with restricted roles, such as Contributors, to create published posts and even attribute them to other users without proper authorization.

Detection Guidance

Check the installed version of the Duplicate Post plugin using WordPress admin panel or run: wp plugin list --name=duplicate-post. If the version is 1.5.8 or earlier, the system is vulnerable.

Impact Analysis

This vulnerability could allow unauthorized users to publish posts on your WordPress site, potentially leading to content manipulation, misinformation, or unauthorized attribution of posts to other users. It undermines the intended access controls set by site administrators.

Mitigation Strategies

Update the Duplicate Post plugin to version 1.5.8 or later immediately. If updating is not possible, consider disabling the plugin until an update is applied.
