Gemini Breaks: Users Report System Prompt Leaks and Personal Information Exposure

Japanese users and developers discovered Google's Gemini leaking system prompts and what appeared to be other users' personal information — a potentially serious privacy incident during a week when Google also launched a new model.

Multiple users reported Tuesday that Google's Gemini was exhibiting alarming behavior: exposing internal system instructions and, in some cases, outputting what appeared to be other users' personal information. The issue was first flagged prominently by Japanese users, with @__ShimoRin__ reporting that Gemini was "broken" and "spitting out personal information of strangers." Developer @BenjaminDEKR confirmed from the English-language side that "system instructions appear to be leaking," suggesting the problem was not localized to one language or region.
