The low EPSS (<1%) and absence from the KEV catalog suggest the exploit may not be actively used yet.

Because the attacker can easily alter the file prior to its execution, exploit complexity is low, giving a high likelihood of successful use if the scenario is present."}}}}, "created": "2026-03-12T10:06:33.499068+00:00", "title": "Privilege Escalation via Executable Replacement in DirectX End\u2011User Runtime Web Installer", "updated": "2026-03-20T14:33:46.715695+00:00", "vendors": ["microsoft", "microsoft$PRODUCT$directx_end-user_runtime_web_installer"]}
