{"id":"CVE-2026-100580","published":"2026-09-26T03:17:05.783","lastModified":"2026-09-28T15:18:41.260","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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-178"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-8xxh-v4vc-qvm4","tags":[]},{"url":"https://www.vulncheck.com/advisories/openclaw-before-2026.7.1-remote-code-execution-via-cron-tool","tags":[]}],"exploitRefs":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-8xxh-v4vc-qvm4","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw in OpenClaw (npm package 'openclaw') before 2026.7.1 allows an attacker to create a persistent cron job that executes arbitrary commands with the privileges of the OpenClaw process user, leading to potential host file and credential access.","exploitability":"Exploitation requires an actor able to steer a tool-enabled agent and knowledge of the mixed-case payload technique.
