A vulnerability has been identified in ModelSim (All versions < V2025.1), Questa (All versions < V2025.1).

This could allow an authenticated local attacker to inject arbitrary code and escalate privileges in installations where administrators or processes with elevated privileges launch the script from a user-writable directory.
