CVE-2026-4245

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

Published Aug 22, 2026 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed
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.
