OpenClaw has Canvas route hardening for mixed-trust deployments
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)
