This is due to the six_storage_create_wp_user() AJAX handler being registered on wp_ajax_nopriv_six_storage_create_wp_user without any nonce, capability, credential, or ownership verification, while calling wp_set_current_user() and wp_set_auth_cookie() for any WordPress user resolved by the attacker-supplied email address. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, by submitting that user's email address.","published":"2026-08-15T03:16:47.670","modified":"2026-08-15T03:16:47.670","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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/6storage-rentals/tags/2.27.0/inc/Base/Six_Storage_DashboardController.php#L14"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.27.0/inc/Base/Six_Storage_DashboardController.php#L3834"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.27.0/inc/Base/Six_Storage_DashboardController.php#L3905"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/94e987be-bdfc-4691-b250-2b7d7249df0a?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-15T03:16:47.670"}}
