GHSA-mqr9-vqhq-3jxw OpenClaw Windows Scheduled Task script generation allowed local command injection via unsafe cmd argument handling

• npm openclaw: < 2026.2.19 → fixed in 2026.2.19

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.
