CVE ID : CVE-2026-2301<\/p>\n
Published : Feb. 25, 2026, 10:16 a.m. | 51\u00a0minutes ago<\/p>\n
Description : 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.<\/p>\n
Severity: 4.3 | MEDIUM<\/p>\n
