CVE-2021-34481 is a Windows Print Spooler vulnerability in which the service improperly performs privileged file operations. Exploitation can allow arbitrary code execution in the context of NT AUTHORITY\SYSTEM. Although some reporting initially described the issue as local privilege escalation, Microsoft classified it as remote code execution, and public research indicated it could be abused through print driver installation and Point and Print-related behavior to transition from low privileges to SYSTEM on affected Windows systems. The flaw is part of the broader 2021 Print Spooler vulnerability cluster often associated with PrintNightmare-related attack paths.
