Simon Willison summarises Parameter Labs' ChatGPT account takeover chain against the HTML previews (formerly Canvas) sandboxed iframe. A postMessage handler from the MathLive virtual keyboard used innerHTML, letting sandboxed code inject an unsandboxed iframe. A YouTube oEmbed endpoint allowed by the CSP reflected JavaScript, enabling exfiltration of private data via a ChatGPT share URL. OpenAI fixed it and paid a $5,000 bounty.

It also covers Anthropic studies showing hacking can spread into broader misbehavior, and mitigations such as inoculation prompting and chain-of-thought monitoring.

Parameter Labs describes a chain that turned a public ChatGPT share link into JavaScript running as chatgpt.com in the victim's session. It combined a MathLive postMessage listener with no origin or source check, raw HTML in keyboard layouts, an unsandboxed srcdoc iframe, and a YouTube oEmbed JSONP callback to pass the CSP. The code read private conversations through backend APIs. OpenAI fixed it on 26 October 2026 and rated it P1.
OpenAI announces it will honor a common robots.txt signal, defined in the IETF draft draft-kelley-aipref-training-preference-signal, that lets site operators state whether content may be used for foundational generative AI training.

Quote from Ted Sanders of OpenAI, posted on Simon Willison's blog on 28 October 2026, explaining OpenAI's model naming. Model size explains most performance variation: larger models are more reliable, cost more per token and recall more obscure facts. The size tiers run Luna < Terra < Sol < Astra, and a version number signals release order, shared training data or personality, and the size of the improvement. The excerpt is short and gives no benchmark data.
