⚠️ Risk & Real-World Impact
Worst Case
Attackers could impersonate administrators or trusted users to spread misinformation, issue false commands, or conduct social engineering attacks during sensitive meetings, potentially leading to data breaches or operational disruption.
Likely Case
Attackers forge messages from other participants to spread confusion, misinformation, or malicious links during video conferences, undermining trust in communication.
If Mitigated
With proper network segmentation and monitoring, impact is limited to message integrity issues within specific conference sessions.
🎯 Exploit Status
Exploitation requires access to a Mirotalk session but doesn't require authentication to forge messages once in a session.

🔍 How to Verify
Check if Vulnerable:
Check if your Mirotalk deployment uses code from before commit c21d58 by examining the git commit history or version information.Check Version:
git log --oneline -1 (if deployed from git) or check package/version files in your deploymentVerify Fix Applied:
Verify the deployment uses commit c21d58 or later by checking the commit hash or version, and test that chat messages properly validate sender identities.📡 Detection & Monitoring
Log Indicators:
- Chat messages with mismatched sender IDs and display names
- Multiple messages from same user with different sender identifiers
Network Indicators:
- Unusual chat message patterns in WebRTC data channels
- Chat messages with spoofed sender metadata
SIEM Query:
Search for chat log entries where sender_name != expected_user_name OR where message metadata shows inconsistencies
