When an administrator subsequently opens the poisoned customer record and clicks Update Customer, `SaveCustomer::handleRequest()` passes the stored `wp_user_id` and attacker-supplied email to `wp_update_user()` \u2014 succeeding because `LinkedAccount::canChange()` unconditionally returns true when the acting user holds the `edit_users` capability \u2014 thereby overwriting the targeted administrator's email address and enabling full account takeover via a standard WordPress password-reset request. Successful exploitation requires an administrator to open and save the poisoned record, and the attacker must know or guess a valid administrator user ID (such as the default user ID 1)."}], "lastModified": "2026-10-31T08:16:47.893", "sourceIdentifier": "security@wordfence.com"}
