CVE-2026-100537

OpenClaw before 2026.8.1 Authentication Bypass via Active Memory

Published Sep 26, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed
Description
OpenClaw (npm package 'openclaw') before 2026.8.1 fails to apply the originating requester's effective tool policy during Active Memory automatic recall. In deployments that use Active Memory together with requester-specific tool rules, deterministic and hidden recall paths can retrieve durable memory and inject it into the agent's context even when toolsBySender explicitly denies that requester access to the memory tools (memory_search, memory_get). As a result, an admitted but denied sender can receive information derived from durable memory in the agent's response without directly invoking any memory tool. The issue is fixed in 2026.8.1.
