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.","published":"2026-08-15T07:16:19.120","modified":"2026-08-15T07:16:19.120","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L141"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L153"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L276"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wholesale-market/tags/2.2.2/addons/wholesale-request/include/class-wholesale-user-register-addon.php#L30"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/abd59d7a-e7f6-440d-9c2a-00266c0dcbff?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-15T07:16:19.120"}}
