{"id":"CVE-2026-12144","summary":"Wholesale for WooCommerce \u003c= 2.0.5 - Authenticated (Author+) Privilege Escalation via 'user_role_set' Parameter","details":"The Wholesale for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.0.5. This is due to the `save_requests_meta()` function applying only `sanitize_text_field()` to the `user_role_set` POST parameter before passing it directly to `WP_User::add_role()`, with no allowlist validation against permitted wholesale roles and no capability check such as `current_user_can('promote_users')` or `current_user_can('manage_options')`. This makes it possible for authenticated attackers with author-level access and above to escalate their privileges to administrator by supplying `administrator` as the `user_role_set` value in a crafted request. The function is gated only by a nonce (`request_user_role_nonce`) that is rendered in the meta box on the `wwp_requests` post edit screen; because the post type is registered with `capability_type =\u003e 'post'`, any author-level user who has authored a `wwp_requests` post — such as one created via the wholesale registration form — can access this nonce and submit the role-assignment request.","modified":"2026-10-06T02:35:39.549631198Z","published":"2026-07-29T01:29:41.564Z","database_specific":{"cna_assigner":"Wordfence","cwe_ids":["CWE-269"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/12xxx/CVE-2026-12144.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"last_affected":"2.0.5"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/12xxx/CVE-2026-12144.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12144"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/woo-wholesale-pricing/tags/2.0.5/inc/class-wwp-wholesale-requests.php#L274"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/woo-wholesale-pricing/tags/2.0.5/inc/class-wwp-wholesale-requests.php#L369"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/woo-wholesale-pricing/tags/2.0.5/inc/class-wwp-wholesale-requests.php#L397"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3621257%40woo-wholesale-pricing&new=3621257%40woo-wholesale-pricing"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/327a155c-7a7d-494d-94d1-f7e7ee8927f0?source=cve"}],"affected":[{"package":{"name":"woo-wholesale-pricing","ecosystem":"WordPress:Plugin"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.0.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-12144.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
