{"id":"CVE-2026-1499","state":"PUBLISHED","title":"WP Duplicate <= 1.1.8 - Authenticated (Subscriber+) Arbitrary File Upload via 'process_add_site' AJAX Action","description":"The WP Duplicate plugin for WordPress is vulnerable to Missing Authorization leading to Arbitrary File Upload in all versions up to and including 1.1.8. This is due to a missing capability check on the `process_add_site()` AJAX action combined with path traversal in the file upload functionality. This makes it possible for authenticated (subscriber-level) attackers to set the internal `prod_key_random_id` option, which can then be used by an unauthenticated attacker to bypass authentication checks and write arbitrary files to the server via the `handle_upload_single_big_file()` function, ultimately leading to remote code execution.","publishedAt":"2026-02-06T08:25:25.712Z","updatedAt":"2026-04-14T15:12:22.866Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["revmakx WP Duplicate – WordPress Migration Plugin"],"affected":[{"vendor":"revmakx","product":"WP Duplicate – WordPress Migration Plugin","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/11bb7190-023b-45e1-99a5-7313c489ef45?source=cve","https://plugins.trac.wordpress.org/browser/local-sync/trunk/admin/class-local-sync-admin.php#L422","https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/admin/class-local-sync-admin.php#L422","https://plugins.trac.wordpress.org/browser/local-sync/trunk/includes/class-local-sync-handle-server-requests.php#L389","https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/includes/class-local-sync-handle-server-requests.php#L389","https://plugins.trac.wordpress.org/browser/local-sync/trunk/admin/class-local-sync-files-op.php#L843","https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/admin/class-local-sync-files-op.php#L843","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3452904%40local-sync&old=3400317%40local-sync&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1499.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1499","state":"PUBLISHED","datePublished":"2026-02-06T08:25:25.712Z","dateUpdated":"2026-04-14T15:12:22.866Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-27T17:54:40.763Z"},"containers":{"cna":{"title":"WP Duplicate <= 1.1.8 - Authenticated (Subscriber+) Arbitrary File Upload via 'process_add_site' AJAX Action","descriptions":[{"lang":"en","value":"The WP Duplicate plugin for WordPress is vulnerable to Missing Authorization leading to Arbitrary File Upload in all versions up to and including 1.1.8.
