Short explanation
Nezha 1.0.0 through 2.3.15 contains a memory exhaustion vulnerability in the dashboard file manager WebSocket endpoint. Because fmStream never calls SetReadLimit, message size remains unbounded. Authenticated users can trigger an OOM kill that drops all agent monitoring.
Authenticated users can send one oversized binary message to the WebSocket endpoint, triggering an OOM kill and interrupting all agent monitoring capabilities.
What should be done?
- Follow vendor advisories
- Upgrade nezha to version 2.3.15 or later
- Apply the patch commits
