Executive Summary

CVE-2026-41910 is a vulnerability in OpenClaw versions before 2026.4.8 where the /allowlist endpoint does not enforce owner-only restrictions for cross-channel allowlist write operations.

This means that an authorized user who is not the owner of a channel can bypass access controls and modify the allowlist of channels they do not own, violating the intended trust model of the system.

Impact Analysis

The vulnerability allows an authorized non-owner to perform unauthorized modifications to allowlists on channels they do not own.

This can lead to a breach of the intended trust model within OpenClaw, potentially allowing unauthorized access or control over channel permissions.

However, the overall severity is rated as Moderate with a CVSS v4 base score of 2.3, indicating a limited impact on integrity and no impact on confidentiality or availability.

Mitigation Strategies

To mitigate the vulnerability CVE-2026-41910, you should upgrade OpenClaw to version 2026.4.8 or later, where the missing owner-only enforcement for cross-channel allowlist writes in the /allowlist endpoint has been fixed.

This update addresses the issue by enforcing proper access controls, preventing authorized non-owner users from modifying allowlists on channels they do not own.

Compliance Impact

The provided information does not specify any direct impact of CVE-2026-41910 on compliance with common standards and regulations such as GDPR or HIPAA.
