Here's my blog post about escaping `<>` in attributes and why it makes mXSS harder to exploit!.
🚨 Heads up for web devs! 🚨 . The HTML spec just got an important update to protect against mutation XSS (mXSS). Find out how escaping < and > in attributes is making the web a safer place.

🔥 A new (more difficult) era for mXSS will come soon! If nothing breaks, Chromium will start escaping "<" and ">" in attributes starting with M138. See for details.
