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.

Analysis

Technical impact

The flaw in the OpenClaw JavaScript package allows an authenticated user who is otherwise denied access to memory tools to retrieve durable memory data indirectly by triggering the Active Memory automatic recall mechanism. The missing enforcement of the originating requester's tool policy lets the attacker obtain information that should have been restricted, resulting in a confidentiality breach of the agent's persistent memory.

Affected Systems

Vendors: OpenClaw. Products: the openclaw npm package. Affected versions: any release before 2026.8.1. Upgrades to 2026.8.1 are required to remove the flaw.

Risk and Exploitability

The vulnerability has a CVSS score of 2.3, indicating moderate severity. No EPSS score is available, and the flaw is not listed in the CISA KEV catalog. Attackers can exploit the bug by sending requests that activate Active Memory recall, bypassing request‑specific tool rules that normally block memory_access. The exploitation requires possessing valid authentication to the OpenClaw system but does not involve code execution or privilege escalation beyond the denied memory tool rights.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade to OpenClaw version 2026.8.1 or later to remove the flaw.
If upgrading is not feasible, disable the Active Memory automatic recall feature or restrict its use to authorized requesters only.
Add an explicit check before memory tool invocation to ensure the originating requester's tool policy is enforced during recall.
