KiviCare – Clinic & Patient Management System (EHR) <= 4.1.2 — Unauthenticated Authentication Bypass via Social Login Token

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under KiviCare – Clinic & Patient Management System (EHR).
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 4.1.3, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch KiviCare – Clinic & Patient Management System (EHR) to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Gibran Abdillah.

The KiviCare – Clinic & Patient Management System (EHR) plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 4.1.2. This is due to the `patientSocialLogin()` function not verifying the social provider access token before authenticating a user. This makes it possible for unauthenticated attackers to log in as any patient registered on the system by providing only their email address and an arbitrary value for the access token, bypassing all credential verification. The attacker gains access to sensitive medical records, appointments, prescriptions, and billing information (PII/PHI breach). Additionally, authentication cookies are set before the role check, meaning the auth cookies for non-patient users (including administrators) are also set in the HTTP response headers, even though a 403 response is returned.
