Untrusted search path in Microsoft Office LTSC 2024 and Microsoft 365 Apps for enterprise allows local users to execute arbitrary code. Microsoft identifies the weakness class but has not disclosed the affected component, searched location, or exact unsafe lookup operation. Low-privilege authenticated local access is required, and successful exploitation runs code in the affected user's context.
