Summary
OpenClaw: node.pair.approve missing callerScopes validation allows low-privilege operator to approve malicious nodes
Details

Summary

The node pairing approval path did not consistently enforce that the approving caller already held every scope requested by the node.

Impact

A lower-privileged operator could approve a pending node request for broader scopes and extend privileges onto the paired node.

Affected Component

src/infra/node-pairing.ts, src/gateway/server-methods/nodes.ts

Fixed Versions

  • Affected: <= 2026.3.24
  • Patched: >= 2026.3.28
  • Latest stable 2026.3.28 contains the fix.

Fix

Fixed by commit 4d7cc6bb4f (gateway: restrict node pairing approvals).

OpenClaw thanks @AntAISecurityLab for reporting.
