That's a major claim. The only thing different in this blog post from my others is that I've embedded an executable python notebook in an iframe.
It's a marimo notebook that runs code using WASM in your browser. That project is open source too, with no exploit as far as I know.
The code for my blog is here : https://github.com/RohanGautam/rohangautam.github.io
If you could point to anything specific to support that claim, would be nice.
