# Windows Print Spooler Elevation of Privilege Vulnerability

The Windows Print Spooler service has a privilege escalation flaw that lets a local user modify a JavaScript constraints file and have it executed with SYSTEM permissions. An attacker with a foothold on a Windows machine gets full control of that machine.

_Summary, check and fix written by a model from the sources; labelled as such._
