CVE-2026-100580OpenClaw before 2026.7.1 Remote Code Execution via cron tool
High 8.8
In plain English
A high-severity security flaw in OpenClaw from OpenClaw. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 28% of all known vulnerabilities).
Official 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.
