CVE-2026-2301 describes a vulnerability in the Post Duplicator plugin for WordPress, affecting all versions up to and including 3.0.8. This flaw allows authenticated attackers with Contributor-level access or higher to insert arbitrary protected post meta keys on duplicated posts. The vulnerability stems from the plugin's direct use of $wpdb->insert() instead of the secure add_post_meta() function, bypassing protection for meta keys starting with an underscore. The vulnerability has a CVSS score of 4.3 (MEDIUM), indicating a low attack complexity and requiring low privileges, but with no confidentiality or availability impact, only low integrity. Attackers can exploit this via the /wp-json/post-duplicator/v1/duplicate-post REST API endpoint to inject sensitive meta keys like _wp_page_template. Currently, there is no evidence of active exploitation, nor are there any public exploit codes available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, consistent with the majority of reported vulnerabilities.
