Please report suspected vulnerabilities privately to zhouhaoyu@linkerbot.cn. Do not open a public GitHub issue for security reports. We aim to acknowledge reports within 5 business days and to coordinate disclosure thereafter.

The Viser viewer serves an unauthenticated HTTP/WebSocket server on a local port (default 8080). Do not expose it to untrusted networks; tunnel over SSH if remote access is required. Treat any deployment that binds the viewer to a non-loopback address as a misconfiguration.
