CVE-2026-4244
4.3
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Summary
The Post Duplicator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the duplicate_post() function in all versions up to, and including, 3.0.11. This is due to the function not verifying that the user has edit_others_posts capability before accepting a selectedAuthorId parameter via the duplicate-post REST endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicated posts attributed to any user, including administrators.
