Post Duplicator <= 3.0.11 - Authorization Bypass to Authenticated (Contributor+) Post Duplication
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.
