{"id":"CVE-2026-4128","state":"PUBLISHED","title":"TP Restore Categories And Taxonomies <= 1.0.1 - Missing Authorization to Authenticated (Subscriber+) Taxonomy Deletion via 'tpmcattt_delete_term' AJAX Action","description":"The TP Restore Categories And Taxonomies plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0.1. The delete_term() function, which handles the 'tpmcattt_delete_term' AJAX action, does not perform any capability check (e.g., current_user_can()) to verify the user has sufficient permissions. While it does verify a nonce via check_ajax_referer(), this nonce is generated for all authenticated users via the admin_enqueue_scripts hook and exposed on any wp-admin page (including profile.php, which subscribers can access). This makes it possible for authenticated attackers, with Subscriber-level access and above, to permanently delete taxonomy term records from the plugin's trash/backup tables by sending a crafted AJAX request with a valid nonce and an arbitrary term_id.","publishedAt":"2026-04-22T07:45:35.777Z","updatedAt":"2026-04-22T12:11:34.991Z","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":["tplugins TP Restore Categories And Taxonomies"],"affected":[{"vendor":"tplugins","product":"TP Restore Categories And Taxonomies","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/53a0749f-86e9-4f62-9de2-a6759c78ba2f?source=cve","https://plugins.trac.wordpress.org/browser/tp-restore-categories-and-taxonomies/trunk/admin/class-tp-move-categories-and-taxonomies-to-trash-admin.php#L474","https://plugins.trac.wordpress.org/browser/tp-restore-categories-and-taxonomies/tags/1.0.1/admin/class-tp-move-categories-and-taxonomies-to-trash-admin.php#L474","https://plugins.trac.wordpress.org/browser/tp-restore-categories-and-taxonomies/trunk/includes/class-tp-move-categories-and-taxonomies-to-trash.php#L169","https://plugins.trac.wordpress.org/browser/tp-restore-categories-and-taxonomies/tags/1.0.1/includes/class-tp-move-categories-and-taxonomies-to-trash.php#L169"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4128.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4128","state":"PUBLISHED","datePublished":"2026-04-22T07:45:35.777Z","dateUpdated":"2026-04-22T12:11:34.991Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-13T14:11:25.304Z"},"containers":{"cna":{"title":"TP Restore Categories And Taxonomies <= 1.0.1 - Missing Authorization to Authenticated (Subscriber+) Taxonomy Deletion via 'tpmcattt_delete_term' AJAX Action","descriptions":[{"lang":"en","value":"The TP Restore Categories And Taxonomies plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0.1.
