> Exfiltrating Your ChatGPT Chat History and Memories With Prompt Injection

In this post we demonstrate how a bypass in OpenAI’s “safe URL” rendering feature allows ChatGPT to send personal information to a third-party server. This can be exploited by an adversary via a prompt injection via untrusted data. If you process untrusted content, like summarizing a website, or analyze a pdf document, the author of that document can exfiltrate any information present in the prompt context, including your past chat history.
