{"id":"CVE-2026-1217","state":"PUBLISHED","title":"Yoast Duplicate Post <= 4.5 - Authenticated (Contributor+) Missing Authorization to Arbitrary Post Duplication and Overwrite","description":"The Yoast Duplicate Post plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the clone_bulk_action_handler() and republish_request() functions in all versions up to, and including, 4.5. This makes it possible for authenticated attackers, with Contributor-level access and above, to duplicate any post on the site including private, draft, and trashed posts they shouldn't have access to. Additionally, attackers with Author-level access and above can use the Rewrite & Republish feature to overwrite any published post with their own content.","publishedAt":"2026-03-18T09:28:28.758Z","updatedAt":"2026-04-08T16:33:31.708Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["yoast Yoast Duplicate Post"],"affected":[{"vendor":"yoast","product":"Yoast Duplicate Post","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/05f175e6-08a9-4199-948c-5bd8b3caaa39?source=cve","https://plugins.trac.wordpress.org/browser/duplicate-post/tags/4.5/src/handlers/bulk-handler.php#L115","https://plugins.trac.wordpress.org/browser/duplicate-post/tags/4.5/src/post-republisher.php#L128"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1217.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1217","state":"PUBLISHED","datePublished":"2026-03-18T09:28:28.758Z","dateUpdated":"2026-04-08T16:33:31.708Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-19T22:11:13.075Z"},"containers":{"cna":{"title":"Yoast Duplicate Post <= 4.5 - Authenticated (Contributor+) Missing Authorization to Arbitrary Post Duplication and Overwrite","descriptions":[{"lang":"en","value":"The Yoast Duplicate Post plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the clone_bulk_action_handler() and republish_request() functions in all versions up to, and including, 4.5.
