AI-Generated

The Post Duplicator plugin for WordPress is vulnerable to an authorization bypass, allowing authenticated users with Contributor-level access and above to create duplicate posts with future or private statuses without proper permissions. This flaw compromises editorial control by enabling unauthorized post duplication and ignores administrator-configured restrictions on post types. WordPress site administrators using this plugin should prioritize patching to mitigate potential abuse and maintain content integrity.

Original NVD Description

The Post Duplicator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.0.11. This is due to the `duplicate_post_permissions()` permission callback only verifying the `duplicate_posts` capability without checking whether the requesting user holds `publish_posts` or other status-gated capabilities. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicate posts with `future` (scheduled, auto-publishes) or `private` status, bypassing editorial review. Additionally, the REST endpoint does not enforce administrator-configured post-type duplication restrictions, allowing duplication of post types that have been explicitly disabled.
