CVE-2026-31994

Local command execution via unsafe task script generation

Published Mar 19, 2026 · Updated Mar 19, 2026

Command injection in OpenClaw before 2026.2.19 allows local users to execute commands through Windows scheduled task scripts. The Windows daemon generator in src/daemon/schtasks.ts writes metacharacters, expansion tokens, and CR/LF sequences into gateway.cmd fields without complete quoting, escaping, or line-break rejection. Exploitation requires control of install-time, runtime, or environment-derived values used to generate the service script, and commands run in the scheduled task context.
