{"id":"CVE-2026-9185","state":"PUBLISHED","title":"6Storage Rentals <= 2.22.0 - Unauthenticated Insecure Direct Object Reference to Arbitrary User Disclosure and Modification via 'userId' Parameter","description":"The 6Storage Rentals plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.22.0 via the `userId` parameter of the `six_storage_get_user_info` and `six_storage_update_profile` AJAX actions. This is due to the `six_storage_getUserInfo()` and `six_storage_updateProfile()` functions being registered on `wp_ajax_nopriv_*` hooks and accepting a tenant identifier directly from `$_POST['userId']` without performing any ownership verification, session binding, or nonce validation to confirm the requester has a legitimate relationship to the supplied ID. This makes it possible for unauthenticated attackers to read and modify arbitrary tenants' profile data — including name, email address, phone number, physical address, and SSN — by supplying an enumerated `userId` value in a crafted request to either handler.","publishedAt":"2026-06-09T03:41:20.509Z","updatedAt":"2026-06-09T15:13:19.602Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["sixstorage 6Storage Rentals"],"affected":[{"vendor":"sixstorage","product":"6Storage Rentals","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.22.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/74fa4240-6f62-4db6-b7e7-56998fc29e42?source=cve","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.22.0/inc/Base/Six_Storage_DashboardController.php#L998","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.22.0/inc/Base/Six_Storage_DashboardController.php#L1955","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.22.0/inc/Base/Six_Storage_DashboardController.php#L11","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.22.0/inc/Base/Six_Storage_DashboardController.php#L995","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.22.0/inc/Base/Six_Storage_DashboardController.php#L1931","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.20.2/inc/Base/Six_Storage_DashboardController.php#L998","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.20.2/inc/Base/Six_Storage_DashboardController.php#L1955","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.20.2/inc/Base/Six_Storage_DashboardController.php#L11","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.20.2/inc/Base/Six_Storage_DashboardController.php#L995","https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.20.2/inc/Base/Six_Storage_DashboardController.php#L1931"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9185.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9185","state":"PUBLISHED","datePublished":"2026-06-09T03:41:20.509Z","dateUpdated":"2026-06-09T15:13:19.602Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-21T14:57:48.503Z"},"containers":{"cna":{"title":"6Storage Rentals <= 2.22.0 - Unauthenticated Insecure Direct Object Reference to Arbitrary User Disclosure and Modification via 'userId' Parameter","descriptions":[{"lang":"en","value":"The 6Storage Rentals plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.22.0 via the `userId` parameter of the `six_storage_get_user_info` and `six_storage_update_profile` AJAX actions.
