{"id":"CVE-2026-89424","state":"PUBLISHED","title":"Duplicate Post <= 1.5.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'noti_token' Parameter","description":"The Duplicate Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'noti_token' parameter in all versions up to, and including, 1.5.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires that the site owner has enabled the plugin's User Level Permissions for the Subscriber role, as this grants access to the i_saw_this_noti AJAX branch needed to deliver the payload.","publishedAt":"2026-10-01T08:28:45.432Z","updatedAt":"2026-10-01T14:13:50.290Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["inisev Duplicate Post"],"affected":[{"vendor":"inisev","product":"Duplicate Post","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.5.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c475c51e-f01d-4698-822f-5b8df999bf6d?source=cve","https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/menu/notifications.php#L53","https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/menu/notifications.php#L84","https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L1598","https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L1601","https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L15","https://plugins.trac.wordpress.org/changeset?reponame=&new=3709767%40copy-delete-posts%2Ftags%2F1.5.7&old=3652254%40copy-delete-posts%2Ftags%2F1.5.6","https://plugins.trac.wordpress.org/changeset/3709767/copy-delete-posts/trunk/menu/notifications.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/89xxx/CVE-2026-89424.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-89424","state":"PUBLISHED","datePublished":"2026-10-01T08:28:45.432Z","dateUpdated":"2026-10-01T14:13:50.290Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-11T18:30:36.215Z"},"containers":{"cna":{"title":"Duplicate Post <= 1.5.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'noti_token' Parameter","descriptions":[{"lang":"en","value":"The Duplicate Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'noti_token' parameter in all versions up to, and including, 1.5.6 due to insufficient input sanitization and output escaping.
