Authorization Flaw in OpenClaw (CVE-2026-100539)
Summary
Vulnerability in OpenClaw (CVE-2026-100539). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 2026.8.1 or later.
Original description
The description as published by the source.
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.
