Summary
OpenClaw has Windows Lobster shell fallback command injection in constrained fallback path
Details

Summary

On Windows, the Lobster extension previously retried certain spawn failures (ENOENT/EINVAL) with shell: true for wrapper compatibility. In that fallback path, tool-provided arguments could be interpreted by cmd.exe if fallback was triggered.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published version at triage: 2026.2.17
  • Affected range: >= 2026.1.21 <= 2026.2.17
  • Patched version: 2026.2.19 (pre-set for next release)

Fix

The Windows shell fallback was removed. Wrapper compatibility is preserved by resolving .cmd/.bat shims to a concrete Node entrypoint (or executable) and executing with explicit argv (no shell). If a safe entrypoint cannot be resolved, execution now fails closed with a guided error.

Fix Commit(s)

  • ba7be018da354ea9f803ed356d20464df0437916

Severity Context

This issue requires Windows plus fallback-triggering conditions, and argument control through a local operator-defined workflow.

OpenClaw thanks @tdjackey for reporting.
