# DeepSeek seems to be leaking random user chat history > Source: > Published: 2026-05-25 19:15:27+00:00 DeepSeek’s web chat interface appears to be leaking conversations between accounts. When opening the chat, a user encountered chat histories that did not belong to them, suggesting a session isolation failure on DeepSeek’s servers. **Privacy incident** If confirmed, this represents a severe data leak where user chat data is being exposed across sessions. Users are advised to avoid entering sensitive information into DeepSeek chat until the issue is resolved. ## Evidence A recording shows the leak in action: The video demonstrates opening DeepSeek chat and being presented with what appears to be another user’s conversation history, including prompts and responses that the account holder did not create. **What to do** If you use DeepSeek chat, avoid sharing personal, financial, or confidential information until DeepSeek issues a statement. Clear your chat history and consider using alternative services for sensitive conversations.
