⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all chat history including potentially sensitive information, intellectual property, or credentials shared in conversations with the AI assistant.
Likely Case
Unauthorized access to chat data containing code snippets, configuration details, or other proprietary information shared during development sessions.
If Mitigated
Limited exposure if chat data contains only non-sensitive information or if network controls prevent data exfiltration.
🎯 Exploit Status
Exploitation requires the attacker to have access to send messages to the chat interface, but the technique is simple once access is obtained.
