{"id":"CVE-2026-120554","state":"PUBLISHED","title":"Import and export users and customers <= 2.5.11 - Authenticated (Custom+) Privilege Escalation via Non-Atomic Cron Settings Save","description":"The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.5.11 This is due to a non-atomic multi-option write sequence in the `ACUI_Cron::save_settings()` function, which persists `acui_cron_activated`, `acui_cron_configured_by`, `acui_cron_user_id`, and `acui_cron_path_to_file` before reaching the authorization gate that calls `wp_die()` when a non-promoter submits a role. This makes it possible for authenticated attackers holding a custom delegated role with `create_users` but without `promote_users` or `edit_users` to escalate their privileges to Administrator, provided a prior administrator cron-tab save exists and no successful save intervenes before the next unattended cron tick processes the attacker's repointed CSV file.","publishedAt":"2026-11-04T09:26:07.169Z","updatedAt":"2026-11-04T20:12:17.021Z","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":["carazo Import and export users and customers"],"affected":[{"vendor":"carazo","product":"Import and export users and customers","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.5.11","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4db0991f-fc89-411b-b0df-1a11c9ddec1f?source=cve","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L101","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L49","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L166","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L1104","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L909","https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta","https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta/trunk/classes/cron.php"],"weaknesses":["CWE-863"],"ingestedAt":"2026-11-04T20:22:06.437Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/120xxx/CVE-2026-120554.json","commit":"0cd352eb7c92cf64a6476b53a70ff3aaac0f560c","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-120554","state":"PUBLISHED","datePublished":"2026-11-04T09:26:07.169Z","dateUpdated":"2026-11-04T20:12:17.021Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-11-02T16:27:57.644Z"},"containers":{"cna":{"title":"Import and export users and customers <= 2.5.11 - Authenticated (Custom+) Privilege Escalation via Non-Atomic Cron Settings Save","descriptions":[{"lang":"en","value":"The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.5.11 This is due to a non-atomic multi-option write sequence in the `ACUI_Cron::save_settings()` function, which persists `acui_cron_activated`, `acui_cron_configured_by`, `acui_cron_user_id`, and `acui_cron_path_to_file` before reaching the authorization gate that calls `wp_die()` when a non-promoter submits a role.
