Executive Summary

CVE-2026-53844 is a vulnerability in OpenClaw versions before 2026.4.29 where authenticated users can bypass session visibility checks in the shared memory search feature.

This flaw allows attackers to access memory entries that should be restricted to their session by skipping the normal authorization guards.

Essentially, users who should only see certain data in shared memory can exploit this issue to view additional memory entries they are not authorized to access.

Impact Analysis

The vulnerability can lead to unauthorized information disclosure by allowing authenticated users to access memory entries outside their authorized session scope.

This means sensitive or restricted data stored in shared memory could be exposed to users who should not have access, potentially compromising confidentiality.

Until patched, operators are advised to restrict shared memory search to trusted users, keep allowlists narrow, avoid sharing gateways between untrusted users, and disable the affected feature if not needed.

Mitigation Strategies

To mitigate the session visibility check bypass vulnerability in OpenClaw, operators should take the following immediate steps:

• Limit shared memory search access to trusted users only.
• Keep allowlists narrow to reduce exposure.
• Avoid sharing a Gateway between untrusted users.
• Disable the affected shared memory search feature if it is not necessary.

Additionally, apply the available patch by upgrading OpenClaw to version 2026.4.29 or later, where the vulnerability has been fixed.
