Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
OpenClaw（npm 包 'openclaw'）在版本 >= 2026.5.12 且 < 2026.8.1 中存在一个安全漏洞：当已配对的节点被撤销时，系统不会立即使 Canvas HTTP 授权失效。虽然节点撤销操作会使 WebSocket 客户端失效，但在 WebSocket 关闭清理完成之前，Canvas HTTP 授权仍会继续接受并续签之前授予的能力权限。因此，在关闭宽限期内，已被撤销的配对节点仍可对其能力配置的路由行使 Canvas 权限。该问题已在版本 2026.8.1 中得到修复；作为临时应对措施

Vulnerability Title
OpenClaw before 2026.8.1 Canvas Capability Revocation Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
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.
