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.","published":"2026-11-04T10:17:26.300","modified":"2026-11-04T10:17:26.460","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/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L101"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L166"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/cron.php#L49"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L1104"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.5.7/classes/import.php#L909"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3775652/import-users-from-csv-with-meta/trunk/classes/cron.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4db0991f-fc89-411b-b0df-1a11c9ddec1f?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-04T10:17:26.460"}}
