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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.8,"severity":"high","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},{"score":8.8,"severity":"high","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793787446460,"publishedAt":1793784367169,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4db0991f-fc89-411b-b0df-1a11c9ddec1f?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L101"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L49"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L166"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L1104"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L909"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta/trunk/classes/cron.php"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L101"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L166"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L49"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L1104"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L909"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta/trunk/classes/cron.php"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4db0991f-fc89-411b-b0df-1a11c9ddec1f?source=cve"}],"remediation":[],"revision":"9c1c13f471102c609e035d04230c09bfeb236739ae8fd5bcbe60228db6350fcf","sources":[{"modifiedAt":1793784367169,"name":"CNA: Wordfence","retrievedAt":1793786933778,"url":"https://www.cve.org/CVERecord?id=CVE-2026-120554"},{"modifiedAt":1793787446460,"name":"NVD","retrievedAt":1793794572663,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-120554"}],"ssvc":null,"status":"published","title":"Import and export users and customers <= 2.5.11 - Authenticated (Custom+) Privilege Escalation via Non-Atomic Cron Settings Save","updatedAt":1793794572663}
