OpenClaw: node.pair.approve missing callerScopes validation allows low-privilege operator to approve malicious nodes
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
2026.3.28contains the fix.
Fix
Fixed by commit 4d7cc6bb4f (gateway: restrict node pairing approvals).
OpenClaw thanks @AntAISecurityLab for reporting.
