Our Commentary ​

This is a must-read for anyone dabbling in AI-generated UI. The assumption that srcdoc is a safe sandbox is a dangerous one, and this article lays out exactly why. I've seen so many projects just blindly render AI output, and the security implications are terrifying. It's a stark reminder that AI doesn't magically solve security; it often introduces new vectors. We need more content like this, focusing on the practical, messy realities.
