OpenClaw (npm package 'openclaw') before 2026.8.1 fails to revoke memory tool access when an operator hot-disables memory configuration. (CVE-2026-100539)
OpenClaw npm package versions before 2026.8.1 contain a vulnerability where memory tool access is not properly revoked when an operator disables memory configuration during runtime. This allows existing memory_search and memory_get tool instances to continue accessing memory with stale permissions for the remainder of the agent's run. The issue is fixed in version 2026.8.1.
AI Analysis
Technical Summary
The OpenClaw npm package prior to version 2026.8.1 fails to revoke memory tool access when an operator hot-disables memory configuration. Specifically, memory_search and memory_get tool instances retain their enabled state because the execution-time resolver treats explicit disablement as an unavailable snapshot and restores stale authority. This allows continued searching and reading of durable memory during an ongoing agent turn after access revocation. Exploitation requires that memory be disabled while a previously created memory tool instance remains active. The vulnerability is addressed in version 2026.8.1.
Potential Impact
An operator's attempt to disable memory configuration during runtime does not immediately revoke access for existing memory tool instances, allowing continued memory search and read operations for the remainder of the agent's execution turn. The impact is limited to unauthorized continued read access to durable memory, with no integrity or availability impact reported. The CVSS score is low (2.6), reflecting limited impact and higher attack complexity.
Mitigation Recommendations
Upgrade to OpenClaw version 2026.8.1 or later, where this issue is fixed. No other mitigation is indicated. Since this is a package vulnerability, patching the affected software version is the recommended remediation.
