: Always confirm the target device or domain before scanning a QR code for camera pairing.
: Some IP cameras use QR codes for initial setup or network provisioning. Researchers have discovered vulnerabilities (such as those in certain Yi Home Camera models ) where a specially crafted QR code can cause a buffer overflow . If an attacker shows a malicious QR code to your camera, they could potentially execute code remotely and take over the device.

Strict validation whitelist rejects hidden scripts, unformatted parameters, and invalid schemas. Essential Guide to Telegram Web - Undetectable :
Telegram deployed an update specifically targeting the security of their in-app QR scanning engine.
Fortunately, a patch has been developed to address this vulnerability. The fix involves updating the camera's firmware to properly validate QR codes and enhancing the encryption protocol for any communication, including that through Telegram. Users are strongly advised to:
Telegram itself has faced its own set of QR code-related vulnerabilities, which is where the keyword "patched" becomes critical. Several high-severity flaws were discovered in Telegram’s QR code authentication system, primarily tied to its "Telegram Web" and desktop login process. Attackers would create fake phishing sites displaying a legitimate Telegram QR code. When a user scanned it, they would unknowingly authorize the attacker's device instead of their own. One report details how a flaw allowed an attacker to compromise an account by simply scanning a QR code generated to join a group chat, granting them access to messages, files, and the ability to delete history without further authentication.
: More recently, critical vulnerabilities (like ZDI-CAN-30207 ) have been identified that could allow remote code execution via animated stickers or videos sent through the app. These are particularly dangerous as they require no user interaction beyond receiving the message.
