A proof-of-concept (PoC) tool titled "fastprox_eop.exe" has been published, which allows an attacker with low privileges to execute arbitrary commands on a compromised system. The exploit requires user interaction and is applicable to multiple versions of Windows 10.

Impact

Successful exploitation allows a local attacker with low privileges to escalate their permissions to a higher integrity level, facilitating arbitrary command execution on the target system.

Recommendation

  1. Inventory all Windows 10 endpoints to identify systems running versions earlier than those listed in the affected products section.
  2. Deploy the relevant Microsoft security updates to remediate CVE-2026-69451 on all identified vulnerable systems.
  3. Monitor endpoint telemetry for unauthorized execution of "fastprox_eop.exe" or suspicious command lines involving the Fastprox component.
