Technical details
The SureCart plugin before version 4.6.3 fails to validate that the account being modified by a customer update action matches the account that was authorized by permission checks. This privilege escalation vulnerability allows an authenticated subscriber-level user to change arbitrary user email addresses through an insecure direct object reference (IDOR). An attacker can modify an administrator's email, trigger a password reset, and gain full account control. Additionally, the plugin discloses customer identifiers and email addresses to any authenticated user, and permits attacker-controlled customer records to be associated with arbitrary users. The vulnerability is reachable with only subscriber-level authentication and was patched in version 4.6.3.
