CVE-2026-100545— OpenClaw before 2026.8.1 Policy Bypass via Session Filename Generation

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 OpenClaw（npm 包 ）2026.8.1 之前的版本中，在会话内存文件名生成过程中，发送方工具策略的执行存在错误。在受影响的版本中，文件名生成机制会创建一个嵌入式助手，并保留源自发送方策略已移除的工具。当针对可由低信任度发送方访问的代理启用了会话内存文件名生成功能时，模型中介指令可能导致该助手调用超出该发送方有效策略范围的工具；所演示的影响是创建持久化的计划任务。可利用性取决于模型是否执行注入的指令，以及助手暴露了哪些工具。该问题已在 2026.8.1 版本中修复；作为变通方案，应针对可由低信任度发送方

Vulnerability Title
OpenClaw before 2026.8.1 Policy Bypass via Session Filename Generation
Source: CVE Program / CVE List V5
Vulnerability Description
OpenClaw (npm package `openclaw`) before 2026.8.1 incorrectly enforces sender tool policies during session-memory filename generation. In affected versions, filename generation created an embedded helper that retained tools which the originating sender's policy had removed. When session-memory filename generation was enabled for an agent reachable by lower-trust senders, model-mediated instructions could cause the helper to invoke tools outside that sender's effective policy; the demonstrated impact was the creation of persistent scheduled work. Exploitability depends on the model acting on the injected instruction and on which tools the helper exposes. The issue is fixed in 2026.8.1; as a workaround, disable session-memory filename generation for agents reachable by lower-trust senders.
