{"id":"CVE-2026-15451","state":"PUBLISHED","title":"MemberPress Corporate Accounts <= 1.5.39 - Authenticated (Subscriber+) Privilege Escalation via Mass Assignment in Sub-Account Creation","description":"The MemberPress Corporate Accounts plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 1.5.39. 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.","publishedAt":"2026-09-12T12:30:04.807Z","updatedAt":"2026-09-14T15:59:45.456Z","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":["MemberPress MemberPress Corporate Accounts"],"affected":[{"vendor":"MemberPress","product":"MemberPress Corporate Accounts","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.5.39","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ba49bbf9-649b-456e-bab8-9f0f74bdbaee?source=cve","https://memberpress.com/addons/corporate-accounts/"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15451.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15451","state":"PUBLISHED","datePublished":"2026-09-12T12:30:04.807Z","dateUpdated":"2026-09-14T15:59:45.456Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-10T19:35:20.741Z"},"containers":{"cna":{"title":"MemberPress Corporate Accounts <= 1.5.39 - Authenticated (Subscriber+) Privilege Escalation via Mass Assignment in Sub-Account Creation","descriptions":[{"lang":"en","value":"The MemberPress Corporate Accounts plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 1.5.39.
