Summary
OpenClaw has Canvas route hardening for mixed-trust deployments
Details

Summary

This advisory tracks a defense-in-depth hardening for canvas routes. In mixed-trust or network-visible deployments, prior canvas auth/fallback behavior could broaden access beyond intended boundaries.

Deployment Context

OpenClaw’s default model is trusted host + loopback-first access. Some operators intentionally expose canvas routes on LAN/tailnet. This update is aimed at those broader deployment patterns.

What Changed

  • Require explicit token or session-capability authorization for canvas routes.
  • Remove shared-IP fallback paths for canvas access.
  • Tighten bind/fallback behavior to fail closed.

Impact

Risk was highest in non-loopback or mixed-trust environments. In strict single-operator trusted-host setups, practical exposure is lower.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Vulnerable: <= 2026.2.19-2
  • Patched: 2026.2.21 (next release target)
