OpenClaw（npm 软件包 ）在版本 2026.4.5 及更高但低于 2026.8.1 的版本中，当从会话中派生的文本被持久化到会话记忆（session memory）时，可能会丢失原始请求者的权限限制和不可信来源标记。在启用了会话记忆捕获和“做梦”（dreaming，即后台自主处理机制）的部署环境中，一个受到限制的外部发送者（其消息仅被允许使用有限工具处理）可以将指令持久化保存，这些指令随后会被提供给一个拥有更广泛文件和命令执行权限的无监督后台“做梦”代理。这可能导致该代理执行超出原始轮次授权范围的操作，从

Vulnerability Title
OpenClaw before 2026.8.1 Privilege Escalation via Session Memory
Source: CVE Program / CVE List V5
Vulnerability Description
OpenClaw (npm package 'openclaw') versions >= 2026.4.5 and < 2026.8.1 can lose the originating requester's restrictions and untrusted provenance when session-derived text is persisted to session memory. In deployments where session-memory capture and dreaming are enabled, a restricted external sender whose messages are admitted with limited tools can persist instructions that are later supplied to an unattended background (dreaming) agent holding broader file and command capabilities, allowing actions beyond the authority of the original turn and affecting files, commands, or services available to that agent. Exploitation requires the content to be captured, selected for later processing, and followed by the model. The issue is fixed in 2026.8.1.
