CVE-2026-54176 is an account management vulnerability in Laravel Backpack CRUD affecting the account information update flow implemented by MyAccountController::postAccountInfoForm. The flaw allows an authenticated user to change the login email address associated with an account without verifying the current password before the change is accepted. Because the email address functions as the account recovery and authentication identifier, an attacker who obtains temporary or otherwise unauthorized access to a victim account can replace the registered email address and later use the password reset mechanism to regain access and fully take over the account.
