This is due to an incomplete blocklist that correctly restricts capability meta keys for the primary site (e.g., `wp_capabilities`, `wp_user_level`) but fails to block the equivalent meta keys for any other subsite in a WordPress Multisite network (e.g., `wp_2_capabilities`, `wp_2_user_level`), allowing these keys to pass the `in_array()` check and be written directly to user meta via `update_user_meta()`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their privileges to Administrator on any subsite within the Multisite network by submitting a crafted profile update to `/wp-admin/profile.php`. Exploitation requires that an administrator has previously imported a CSV file containing multisite-prefixed capability column headers and has enabled the 'Show fields in profile?' option, which causes those keys to be stored in the `acui_columns` option and exposed as editable fields on the user profile page."}],"title":"Import and export users and customers <= 2.0.8 - Authenticated (Subscriber+) Privilege Escalation via Multisite Capability Meta Fields","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/368cff00-6a86-443e-aec4-4115a229a3c1?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/columns.php#L221"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/columns.php#L221"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/columns.php#L198"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/columns.php#L198"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/helper.php#L150"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/helper.php#L150"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/multisite.php#L21"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/multisite.php#L21"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/columns.php#L221"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/columns.php#L198"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/helper.php#L150"},{"url":"https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/multisite.php#L21"},{"url":"https://plugins.trac.wordpress.org/changeset/3515646"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Di Nhau"}],"timeline":[{"time":"2026-04-25T18:36:36.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-05-01T16:14:05.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-04T16:12:22.466577Z","id":"CVE-2026-7641","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-04T17:52:17.966Z"}}]}}
