What it is

🚨 An unauthenticated RCE vulnerability in the TP-Link Tapo C200 IP camera lets attackers take control as if they were the owner! 🔥 Think of this as a hotel with a front desk that never checks IDs. Anyone can walk in, grab a key, and access all the guest rooms — total chaos! An attacker could gain full control of your IP camera, which means they could spy on your home, access private footage, and potentially use it as a jumping-off point for further attacks. This could lead to devastating privacy breaches and security risks, making it essential to act fast!
