OpenClaw是OpenClaw开源的一个智能人工助理。 OpenClaw 2026.5.20之前版本存在安全漏洞，该漏洞源于权限提升问题，钩子触发的代理运行错误地接收所有者范围的MCP回环权限而非钩子适当范围。攻击者拥有有效的钩子令牌，可以利用/hooks/agent端点导致生成的CLI运行时访问或调用仅限所有者的MCP工具，可能执行特权操作如持久cron状态修改。

Vulnerability Title
OpenClaw < 2026.5.20 - Privilege Escalation via Hook-Triggered CLI MCP Tool Authority
Source: CVE Program / CVE List V5
Vulnerability Description
OpenClaw before 2026.5.20 contains a privilege escalation vulnerability where hook-triggered agent runs incorrectly receive owner-scoped MCP loopback authority instead of hook-appropriate scope. Attackers with a valid hook token can exploit the /hooks/agent endpoint to cause spawned CLI runtimes to access or invoke owner-only MCP tools, potentially executing privileged actions like persistent cron state modifications.
