CVE-2026-27182Public exploitNetwork attack vector

Unauthenticated code execution via UDP keystroke injection

Published Feb 18, 2026 · Updated Feb 18, 2026

Command injection in Student Driver LLC Saturn Remote Mouse Server allows remote attackers to execute code via UDP packets to port 27000. The server accepts unauthenticated JSON Key events, uses them to open the Windows command shell, and types attacker-controlled PowerShell into it. Local-network access to UDP port 27000 is sufficient, and commands run with the server process account’s privileges.
