Exploitation Conditions

Requires an already-authorized non-owner sender operating over an external channel bridged to the OpenClaw Gateway, plus command policy that admits that sender to issue mutations. Exploitation is limited strictly to the persistent global Active Memory on/off toggle; session-level controls and read-only status remain governed by existing command policy and are not affected. Owner privileges are NOT required (that is the bug), but baseline authorized command access to the Gateway is, and no additional user interaction is needed. Only versions before 2026.7.1 are vulnerable.

Impact

This is a genuine but low-severity authorization flaw (CWE-862, missing owner check), not a high-CVSS-but-inflated issue - the vendor CVSS 4.0 of 5.3 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L) is medium and honestly reflects limited impact. The vector shows network reach and low complexity, but exploitation requires PR:L (an already-authorized non-owner sender), which caps the blast radius. Impact is confined to persistently toggling the global Active Memory on/off state - degrading memory recall or re-enabling it against the owner's intent - with no confidentiality/integrity of arbitrary data and no code execution. There is no EPSS score, no CISA KEV listing, and no public PoC provided, so this is no public exploit identified at time of analysis. The 'Authentication Bypass' tag overstates the nature of the issue: this is an authorization (missing owner check) defect on a configuration toggle, not an auth bypass. Net: low real-world priority, patch on normal cadence.

Exploit ScenarioDerived

An OpenClaw Gateway is bridged to an external chat channel where a non-owner user has been granted command access. That authorized-but-non-owner sender issues the global Active Memory toggle mutation, which fails to enforce the owner-only check, letting them persistently disable memory recall for all future sessions (or re-enable global recall the owner wanted off). No public exploit code is identified at time of analysis.

AnalysisAIv1 – Sep 26, 2026

OpenClaw agent gateway installations before 2026.7.1 expose a missing owner authorization check that permits an authenticated non-owner sender on a bridged external channel to persistently enable or disable the global Active Memory setting, thereby disabling memory recall for future sessions or re-enabling global recall when the owner expected it to remain disabled. The flaw is limited to persistent global on/off mutations-session-level controls and read-only status remain governed by existing command policy-and carries a vendor CVSS 4.0 score of 5.3 with only low impact across confidentiality, integrity, and availability. No public exploit code or active exploitation has been identified at time of analysis, and the vendor has released a patch in version 2026.7.1.

RemediationAI

Upgrade OpenClaw to version 2026.7.1 or later, which contains the vendor fix for the missing owner check on Active Memory global toggles. Apply the update via npm (e.g., npm install openclaw@2026.7.1) and verify the deployed gateway reports the new version. If immediate upgrade is not possible, restrict the command policy for external-channel senders so that only the owner can issue Active Memory toggle mutations; this compensating control will disable the ability for non-owner senders to change global memory recall settings-the intended security posture-but may be inconvenient if non-owner administrators legitimately managed that toggle. Review audit logs for unexpected changes to Active Memory state prior to patching. Vendor advisory: https://github.com/openclaw/openclaw/security/advisories/GHSA-xw9g-7xvv-gcjc.

Technical ContextAI · show details

CWE-862 (Missing Authorization) in OpenClaw's Active Memory global toggle mutation handlers. OpenClaw is an npm-distributed agent gateway with a Node.js runtime that bridges external messaging channels to AI agent sessions; the Active Memory feature controls whether agents may recall prior session context globally. Because the mutation endpoint omitted an owner-privilege check, any sender already authorized by command policy to issue mutations could alter the persistent global state. The vulnerability is confined to the on/off mutations for Active Memory; session-scoped controls and read-only status queries were not affected, which limits the blast radius to availability and integrity of memory recall settings. Affected CPE: cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:*:*:* covering all versions before 2026.7.1.

DescriptionCVE.org

OpenClaw is an npm-distributed agent gateway. In versions before 2026.7.1, the global Active Memory toggle mutations could omit owner checks. An authorized non-owner external-channel sender could therefore persistently enable or disable Active Memory for the Gateway, disabling memory recall for future sessions or re-enabling global recall where the owner expected it to remain disabled. The issue is limited to persistent global on/off mutations; session-level controls and read-only status remain governed by existing command policy. The issue is fixed in version 2026.7.1. (Suggested title: "OpenClaw before 2026.7.1 missing owner authorization check on Active Memory global toggles".)
