Affected: OpenClaw

OpenClaw versions prior to 2026.2.19 contain a local command injection vulnerability in Windows scheduled task script generation due to unsafe handling of cmd metacharacters and expansion-sensitive characters in gateway.cmd files. Local attackers with control over service script generation arguments can inject arbitrary commands by providing metacharacter-only values or CR/LF sequences that execute unintended code in the scheduled task context.

Affected: npm: openclaw

### Summary OpenClaw Windows Scheduled Task script generation allowed unsafe argument handling in generated `gateway.cmd` files. In vulnerable versions, cmd metacharacter-only values could be emitted without safe quoting/escaping, which could lead to unintended command execution when the scheduled task runs.

### Details The issue affected Windows daemon startup script generation in `src/daemon/schtasks.ts`.

Vulnerable behavior included: - Incomplete cmd argument quoting for metacharacter-only values. - Incomplete handling of cmd expansion-sensitive characters in script arguments. - Missing CR/LF guards for script-rendered fields.

The fix hardens Windows script generation by: - Separating schtasks argument quoting from batch script argument quoting. - Quoting cmd metacharacter arguments and escaping `%` / `!` expansion cases. - Rejecting CR/LF in command arguments, task descriptions, and rendered environment assignments. - Adding regression tests for metacharacter and line-break injection paths.

### Impact This issue is local to Windows deployments and requires control over values that feed service script generation (for example install-time/runtime arguments or environment-derived values). It can result in unintended command execution in the scheduled task context.
