What it is

🚨 A nifty bug allows attackers to elevate their privileges through the Windows DWM Core Library! Just like that, they could gain access to the keys of the kingdom without breaking a sweat! ⚡ Think of it like an employee sneaking into the manager's office by simply disguising themselves as a janitor.

This could mean anything from stealing sensitive data to installing malicious software, making it a serious threat to your security!
