CVE-2026-1217

The Yoast Duplicate Post plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the clone_bulk_action_handler() and republish_request() functions in all versions up to, and including, 4.5. This makes it possible for authenticated attackers, with Contributor-level access and above, to duplicate any post on the site including private, draft, and trashed posts they shouldn't have access to. Additionally, attackers with Author-level access and above can use the Rewrite & Republish feature to overwrite any published post with their own content.

Yoast Duplicate Post [duplicate-post] < 3.2.4

The Duplicate Post plugin was vulnerable to Authenticated Stored Cross-Site Scripting (XSS). However, the POST request had a CSRF nonce that was verified, and no user's without the unfiltered_html capability, such as Author or Subscriber, were able to access the affected Duplicate Post settings page. Therefore, this vulnerability would be very difficult to exploit in the real world. The risk of this issue is very low.
