Will ChatGPT data leakage expose my conversations?

Yes, especially if you've run code on sensitive uploads — attackers can exfiltrate via hidden outbound channels in the runtime.

How does the hidden outbound channel work in ChatGPT?

Malicious code in the interpreter encodes and sends data to external servers, bypassing sandbox network restrictions.

Is it safe to use ChatGPT's code interpreter now?

Avoid sensitive data until OpenAI patches; stick to non-confidential tasks.
