Cron Command Injection in OpenClaw npm Package

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
OpenClaw (npm package 'openclaw') before 2026.7.1 improperly handles case sensitivity in the model-facing cron tool: a mixed-case payload kind can pass the agent-facing shell-execution guard and later normalize into a command job. An actor able to steer a tool-enabled agent can therefore create a persistent cron job that executes attacker-selected commands with the privileges of the OpenClaw process user, resulting in access to host files and credentials and impact to scheduled service availability. The issue is limited to cron jobs created or edited through the model-facing cron tool; direct CLI and authorized Gateway scheduling surfaces are trusted operator controls. Fixed in 2026.7.1.

Executive Summary

CVE-2026-100580 is a vulnerability in the OpenClaw npm package before version 2026.7.1. It involves improper handling of case sensitivity in the model-facing cron tool. Attackers can exploit mixed-case payloads to bypass security checks and create persistent cron jobs that execute malicious commands with the privileges of the OpenClaw process user.

Detection Guidance

Check OpenClaw cron jobs for mixed-case payloads using commands like grep -r 'openclaw' /etc/cron* or inspect job configurations in the OpenClaw interface. Look for any unauthorized or suspicious cron entries created through the model-facing tool.

Impact Analysis

This vulnerability allows attackers to execute arbitrary commands on the host system with the privileges of the OpenClaw process user. This can lead to unauthorized access to host files and credentials, as well as disruption of scheduled services through malicious cron jobs.

Mitigation Strategies

Upgrade OpenClaw to version 2026.7.1 or later immediately. Review and remove any suspicious cron jobs created through the model-facing tool. Ensure direct CLI and authorized Gateway scheduling methods are used for future cron job management.
