Summary

The Lobster extension tool execution path used a Windows shell fallback (shell: true) after spawn failures (EINVAL/ENOENT). In that fallback path, shell metacharacters in command arguments can be interpreted by the shell, enabling command injection.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.2.17
Latest confirmed affected published version: 2026.2.17
Patched version: 2026.2.19

Technical Details

In affected releases (including v2026.2.17), extensions/lobster/src/lobster-tool.ts retried subprocess launch with shell: true on Windows for EINVAL/ENOENT spawn errors. The fix removes shell fallback and resolves Windows wrappers to explicit executable/script argv execution.
