Our recommendation
- Confirm with WizLearn in writing that your tenant is patched and request the fixed version number.
- Keep Google and Facebook social login disabled until the vendor confirms the fix.
- Review admin account lists and login logs since early October 2026 for unexpected admin or social login activity, focusing on /wizlearnlms/Login/Login.aspx.
- Force a password reset for admin accounts and for accounts that used social login.
- Restrict admin access to the LMS by IP address or VPN where the product allows it.
- Recheck NVD, CISA KEV and GitHub for updates over the coming days.
