Summary
Researchers discovered a vulnerability in ChatGPT that could leak sensitive user data (like medical records, financial information, and internal documents) from conversations without the user's knowledge or permission. Although OpenAI has since fixed the issue, the discovery highlights an important lesson: AI tools should not be automatically trusted to be secure just because they are popular or widely used.
