Summary

OpenClaw: Existing WS sessions survive shared gateway token rotation

Details

Impact

Existing WS sessions survive shared gateway token rotation.

Rotating the shared gateway token did not disconnect existing shared-token WebSocket sessions.

OpenClaw is a user-controlled local assistant. This advisory is scoped to the OpenClaw trust model and does not assume a multi-tenant service boundary.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.4.1
Patched versions: 2026.4.8
