OpenClaw npm Package Policy Bypass in Group Channels

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
OpenClaw (npm package `openclaw`) before 2026.7.1 does not enforce the documented owner-only requirement for persistent `/activation` policy changes in group channels. An authorized non-owner channel sender can change whether the agent requires mention-based activation, causing the agent to respond more broadly in the group (exposing its responses to additional group traffic) or suppressing expected activation behavior until an owner restores the intended setting. The issue is fixed in version 2026.7.1.

Executive Summary

OpenClaw before version 2026.7.1 has a missing authorization check in the /activation endpoint. This allows an authorized non-owner channel sender to change persistent policy settings that control whether the agent requires mention-based activation in group channels. The agent may then respond more broadly to group traffic or suppress expected activation behavior until an owner restores the intended configuration.

Detection Guidance

To detect this vulnerability, check the installed version of the openclaw npm package. Run: npm list openclaw. If the version is before 2026.7.1, the system is vulnerable. Additionally, review group channel activation settings for unauthorized changes to mention-based activation policies.

Impact Analysis

An attacker with authorized non-owner access could modify group activation settings, causing the agent to either respond to more group messages than intended or stop responding when expected. This could lead to unintended data exposure, reduced functionality, or operational disruptions in group channels until an owner corrects the settings.

Compliance Impact

This vulnerability could lead to unauthorized data exposure or improper access controls in group channels, potentially violating GDPR's data protection principles or HIPAA's access control requirements. Organizations using OpenClaw in regulated environments should upgrade to version 2026.7.1 or later to maintain compliance.

Mitigation Strategies

Upgrade the openclaw package to version 2026.7.1 or later using: npm install openclaw@2026.7.1. Disable activation-setting commands in shared channels before upgrading. Verify group activation configurations after untrusted command activity to ensure intended settings are restored.
