CVE-2026-2301 (GCVE-0-2026-2301)

Title
Post Duplicator <= 3.0.8 - Missing Authorization to Authenticated (Contributor+) Protected Post Meta Insertion via 'customMetaData' Parameter
Summary
The Post Duplicator plugin for WordPress is vulnerable to unauthorized arbitrary protected post meta insertion in all versions up to, and including, 3.0.8. This is due to the `duplicate_post()` function in `includes/api.php` using `$wpdb->insert()` directly to the `wp_postmeta` table instead of WordPress's standard `add_post_meta()` function, which would call `is_protected_meta()` to prevent lower-privileged users from setting protected meta keys (those starting with `_`). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary protected post meta keys such as `_wp_page_template`, `_wp_attached_file`, and other sensitive meta keys on duplicated posts via the `customMetaData` JSON array parameter in the `/wp-json/post-duplicator/v1/duplicate-post` REST API endpoint.

Title
Post Duplicator <= 2.36 - Authenticated (Contributor+) Protected Post Disclosure
Summary
The Post Duplicator plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.36 via the mtphr_duplicate_post() due to insufficient restrictions on which posts can be duplicated. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract data from password protected, private, or draft posts that they should not have access to by duplicating the post.

CVE-2024-12472 (GCVE-0-2024-12472)

Title
Post Duplicator <= 2.36 - Authenticated (Contributor+) Protected Post Disclosure
Summary
The Post Duplicator plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.36 via the mtphr_duplicate_post() due to insufficient restrictions on which posts can be duplicated. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract data from password protected, private, or draft posts that they should not have access to by duplicating the post.
Severity ?
