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.

Impact

OpenClaw fails to revoke access to memory tools when an operator hot‑disables the memory configuration. A memory_search or memory_get instance that was created before the disable retains the enabled state because the runtime treats the explicit disable as a snapshot and restores a stale authority. Consequently, during an existing run the model can continue searching and reading durable memory after the operator has revoked that access, exposing data that should no longer be available. The flaw is a control‑flow weakness that allows unauthorized memory reads in the short window of an agent run.

Affected Systems

The vulnerability affects the OpenClaw npm package (openclaw) in all releases before version 2026.8.1. No additional vendor or product variations are listed.

Risk and Exploitability

The CVSS score of 2.1 indicates a low severity impact, and the EPSS score is not available, while the vulnerability is not listed in the CISA KEV catalog. Attacks would require an operator with the ability to disable memory configuration while a previously created memory tool remains active, and the effect is limited to the remainder of the current agent run. The limited scope and requirement for in‑place operator action suggest a low likelihood of exploitation in typical deployments.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the openclaw package to version 2026.8.1 or later to apply the fix for memory access control.
  • Confirm that any memory tools created before a memory configuration change are terminated or refreshed; restarting agents after disabling memory prevents stale tool references.
  • Audit agent logs to ensure memory_search and memory_get activities stop after memory is disabled, confirming the control flow has been restored.
