What it is

⚠️ A sneaky flaw in the DNS server could let attackers execute arbitrary code just by sending a crafted NAPTR query! Think of it like a restaurant where the chef blindly follows a phone order without verifying the details.

This could compromise the entire network, putting your systems and users at risk!
