{"id":"CVE-2026-4244","state":"PUBLISHED","title":"Post Duplicator <= 3.0.11 - Missing Authorization to Authenticated (Contributor+) Post Duplication with Arbitrary Author Attribution","description":"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.","publishedAt":"2026-08-22T12:28:43.454Z","updatedAt":"2026-08-24T13:01:22.632Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["metaphorcreations Post Duplicator"],"affected":[{"vendor":"metaphorcreations","product":"Post Duplicator","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.0.11","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/64553742-ff2b-40e9-92c3-3458a9f988a2?source=cve","https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L728","https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L520","https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L550","https://plugins.trac.wordpress.org/changeset/3485579/"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4244.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4244","state":"PUBLISHED","datePublished":"2026-08-22T12:28:43.454Z","dateUpdated":"2026-08-24T13:01:22.632Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-15T21:44:09.826Z"},"containers":{"cna":{"title":"Post Duplicator <= 3.0.11 - Missing Authorization to Authenticated (Contributor+) Post Duplication with Arbitrary Author Attribution","descriptions":[{"lang":"en","value":"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.
