NVD Description

Note: Versions mentioned in the description apply only to the upstream openclaw package and not the openclaw package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

OpenClaw (npm package 'openclaw') versions >= 2026.5.12 and < 2026.8.1 do not immediately invalidate Canvas HTTP authorization when a paired node is revoked. Node revocation invalidates the WebSocket client, but Canvas HTTP authorization continues to accept and renew the previously granted capability until WebSocket close cleanup completes. As a result, a revoked paired node can continue exercising its Canvas capability against the capability's configured routes during the close grace period. The issue is fixed in 2026.8.1; as a workaround, restart the Gateway after revoking a node that has Canvas access.
