The record

HCL Traveler for Microsoft Outlook (HTMO) is susceptible to vulnerabilities due to .NET Framework 4.5 being out of service. Since .NET Framework 4.5 has reached end-of-life and no longer receives security updates, it may expose the application to publicly known security weaknesses through vulnerable third-party components.
