CVE-2021-34527 (PrintNightmare)

CVE-2021-34527, known as PrintNightmare, is a serious security vulnerability affecting Windows systems that use the Print Spooler service, which manages printing tasks. This flaw allows attackers to run malicious code with system-level privileges, potentially enabling them to install software, access data, or take control of affected machines remotely.
