This is due to the update_user_profile() function in controllers/flutter-user.php processing the 'meta_data' JSON parameter without any allowlist, blocklist, or validation of meta keys. The function reads raw JSON from php://input (line 1012), decodes it (line 1013), authenticates the user via cookie validation (line 1015), and then directly iterates over the user-supplied meta_data array passing arbitrary keys and values to update_user_meta() (line 1080) with no sanitization or restrictions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary user meta fields on their own accounts, including sensitive fields like wp_user_level (to escalate to administrator-level legacy checks), plugin-specific authorization flags (e.g., _wpuf_user_active, aiowps_account_status), and billing/profile fields with unsanitized values (potentially enabling Stored XSS in admin contexts). Note that wp_capabilities cannot be directly exploited this way because it requires a serialized array value, but wp_user_level (a simple integer) and numerous plugin-specific meta keys are exploitable."}],"title":"MStore API <= 4.18.3 - Authenticated (Subscriber+) Insecure Direct Object Reference to Arbitrary User Meta Update","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a77bc126-4dbd-4a26-b98c-946341d4282f?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/mstore-api/trunk/controllers/flutter-user.php#L1078"},{"url":"https://plugins.trac.wordpress.org/browser/mstore-api/trunk/controllers/flutter-user.php#L1080"},{"url":"https://plugins.trac.wordpress.org/browser/mstore-api/tags/4.18.3/controllers/flutter-user.php#L1080"},{"url":"https://plugins.trac.wordpress.org/browser/mstore-api/trunk/controllers/flutter-user.php#L1012"},{"url":"https://plugins.trac.wordpress.org/browser/mstore-api/tags/4.18.3/controllers/flutter-user.php#L1012"},{"url":"https://plugins.trac.wordpress.org/browser/mstore-api/tags/4.18.3/controllers/flutter-user.php#L1078"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3494266%40mstore-api&new=3494266%40mstore-api&sfp_email=&sfph_mail="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-639 Authorization Bypass Through User-Controlled Key","cweId":"CWE-639","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Osvaldo Noe Gonzalez Del Rio"}],"timeline":[{"time":"2026-03-05T01:27:28.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-04-08T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-09T12:59:03.231688Z","id":"CVE-2026-3568","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-09T12:59:11.618Z"}}]}}
