GHSA-MQR9-VQHQ-3JXW
Vulnerability from github – Published: 2026-03-03 21:37 – Updated: 2026-03-19 21:24Summary
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.
