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 'openclaw'）版本 2026.8.1 之前，当操作者热禁用内存配置时，系统未能撤销对内存工具的访问权限。已存在的 memory_search 和 memory_get 工具实例仍保留创建时捕获的启用状态配置，因为执行时解析器将显式禁用操作视为不可用的配置快照，并恢复了过期的权限。因此，在代理轮次（agent turn）已经运行的过程中，即使操作者已撤销访问权限，模型仍可在该次运行的剩余时间内继续搜索和读取持久化内存。 利用此漏洞的前提是：在已创建的内存工具仍处于活跃状态时，

Vulnerability Title
OpenClaw before 2026.8.1 Memory Access Control Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
OpenClaw (npm package 'openclaw') before 2026.8.1 fails to revoke memory tool access when an operator hot-disables memory configuration. Existing memory_search and memory_get tool instances retain the enabled configuration captured at creation time because the execution-time resolver treats explicit disablement like an unavailable configuration snapshot and restores the stale authority. As a result, during an already-running agent turn the model can continue searching and reading durable memory after the operator revoked that access, for the remainder of that run. Exploitation requires memory to be disabled while a previously created memory tool remains active. The issue is fixed in 2026.8.1.
