This is due to a mass assignment vulnerability in the 'add_sub_account_user' function that passes the raw 'userdata' array to 'wp_insert_user' without filtering dangerous keys like role or ID. This makes it possible for authenticated attackers, with subscriber-level access and above who hold a corporate account, to create new administrator accounts or hijack existing administrator accounts by overwriting their email addresses. The vulnerability was partially patched in version 1.5.39."}],"title":"MemberPress Corporate Accounts <= 1.5.39 - Authenticated (Subscriber+) Privilege Escalation via Mass Assignment in Sub-Account Creation","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ba49bbf9-649b-456e-bab8-9f0f74bdbaee?source=cve"},{"url":"https://memberpress.com/addons/corporate-accounts/"}],"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":"andrea bocchetti"}],"timeline":[{"time":"2026-07-10T19:58:56.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-11T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-14T15:59:24.230861Z","id":"CVE-2026-15451","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":"2026-09-14T15:59:45.456Z"}}]}}
