{"id":"CVE-2026-7641","state":"PUBLISHED","title":"Import and export users and customers <= 2.0.8 - Authenticated (Subscriber+) Privilege Escalation via Multisite Capability Meta Fields","description":"The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to and including 2.0.8 via the `save_extra_user_profile_fields()` function. 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.","publishedAt":"2026-05-02T04:27:44.329Z","updatedAt":"2026-05-04T17:52:17.966Z","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":"2.0.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/368cff00-6a86-443e-aec4-4115a229a3c1?source=cve","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/columns.php#L221","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/columns.php#L221","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/columns.php#L198","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/columns.php#L198","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/helper.php#L150","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/helper.php#L150","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/multisite.php#L21","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/multisite.php#L21","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/columns.php#L221","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/columns.php#L198","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/helper.php#L150","https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/multisite.php#L21","https://plugins.trac.wordpress.org/changeset/3515646"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/7xxx/CVE-2026-7641.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-7641","state":"PUBLISHED","datePublished":"2026-05-02T04:27:44.329Z","dateUpdated":"2026-05-04T17:52:17.966Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-01T16:13:55.353Z"},"containers":{"cna":{"title":"Import and export users and customers <= 2.0.8 - Authenticated (Subscriber+) Privilege Escalation via Multisite Capability Meta Fields","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 2.0.8 via the `save_extra_user_profile_fields()` function.
