📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with administrative privileges, allowing installation of persistent malware, data theft, and complete control of the affected system.
Likely Case
Local privilege escalation enabling attackers to execute arbitrary code with elevated permissions, potentially leading to lateral movement within networks.
