OpenClaw: Gateway `device.token.rotate` does not terminate active WebSocket sessions after credential rotation

Summary

Gateway device.token.rotate does not terminate active WebSocket sessions after credential rotation

Current Maintainer Triage

  • Status: open
  • Normalized severity: low
  • Assessment: v2026.3.28 rotates device tokens without disconnecting already-authenticated WebSocket sessions, which is a real but post-compromise revocation gap.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version: 2026.3.31
  • Vulnerable version range: <=2026.3.28
  • Patched versions: >= 2026.3.31
  • First stable tag containing the fix: v2026.3.31

Release Process Note

  • The fix is already present in released version 2026.3.31.
  • This draft looks ready for final maintainer disposition or publication, not additional code-fix work.
