What it is

⚠️ A crafty little misstep in Microsoft XML services lets attackers snoop around your file system via a malicious website! Think of it like a nosy houseguest who somehow discovers which rooms are off-limits, all while pretending to admire the living room. They can peek behind closed doors and check for your most private items without ever stepping inside the house! This vulnerability allows an attacker to ascertain the existence of files on your disk simply by interacting with a specially crafted website. It won’t let them in, but they can gather information about what’s there and potentially exploit that knowledge later. Yikes!
