CVE-2026-15451
The MemberPress Corporate Accounts plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 1.5.39.
Impact
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.
