{"id":"CVE-2026-14279","state":"PUBLISHED","title":"Wholesale Market <= 2.2.2 - Authenticated (Subscriber+) Privilege Escalation via 'role_required' Parameter","description":"The Wholesale Market plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.2.2 via the ced_wholesale_request_send AJAX action. The ced_wholesale_request_send_callback() handler only verifies a nonce (which is exposed to any authenticated user through wp_localize_script on the frontend) and that the caller has a positive user ID, then calls WP_User::add_role() with the client-supplied role_required POST parameter without restricting the value to an allowlist of wholesale roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to Administrator when the site administrator has enabled the 'Assigning requested role directly' option.","publishedAt":"2026-08-15T06:38:10.106Z","updatedAt":"2026-08-18T19:33:27.928Z","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":["cedcommerce Wholesale Market"],"affected":[{"vendor":"cedcommerce","product":"Wholesale Market","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.2.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/abd59d7a-e7f6-440d-9c2a-00266c0dcbff?source=cve","https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L141","https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L153","https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L276","https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L30"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/14xxx/CVE-2026-14279.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-14279","state":"PUBLISHED","datePublished":"2026-08-15T06:38:10.106Z","dateUpdated":"2026-08-18T19:33:27.928Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-30T22:29:09.817Z"},"containers":{"cna":{"title":"Wholesale Market <= 2.2.2 - Authenticated (Subscriber+) Privilege Escalation via 'role_required' Parameter","descriptions":[{"lang":"en","value":"The Wholesale Market plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.2.2 via the ced_wholesale_request_send AJAX action.
