The vulnerability exists because the `six_storage_portal_registration()` AJAX handler — registered on `wp_ajax_six_storage_portal_plugin_registration` — performs no capability check and no nonce verification before writing the caller-supplied `six_storage_online_api_url` POST parameter to the site-wide option of the same name; the unauthenticated `six_storage_create_wp_user()` handler then redeems a transient seeded from that attacker-controlled URL's response and unconditionally calls `wp_set_current_user()` and `wp_set_auth_cookie()` with no ownership or credential verification. This makes it possible for authenticated attackers, with Subscriber-level access and above, to authenticate as any existing WordPress user — including any administrator whose email address is known or guessable — resulting in full site compromise. This issue represents an incomplete fix for a prior vulnerability: the 2.29.0 remediation moved the target email out of POST data into a server-side transient, but because any Subscriber can still overwrite the outbound API URL that populates that transient, the full authentication bypass chain remains exploitable in three AJAX requests."}],"id":"CVE-2026-103883","lastModified":"2026-11-13T18:17:25.023","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","baseScore":8.8,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"exploitabilityScore":2.8,"impactScore":5.9,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-103883","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","timestamp":"2026-11-13T17:16:10.217309Z","version":"2.0.3"}}]},"published":"2026-11-11T12:18:14.700","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.31.0/inc/Base/Six_Storage_DashboardController.php#L14"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.31.0/inc/Base/Six_Storage_DashboardController.php#L4126"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.31.0/inc/Base/Six_Storage_SignInControllerSixStorage.php#L90"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.31.0/inc/Pages/Admin/Six_Storage_WpAdmin.php#L39"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/6storage-rentals/tags/2.31.0/inc/Pages/Admin/Six_Storage_WpAdmin.php#L708"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/67b82539-8582-4bb4-ad4c-b626233b6075?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-287"}],"source":"security@wordfence.com","type":"Secondary"}]}
