CVE-2026-32000
OpenClaw has command injection via Windows shell fallback in Lobster tool execution
Description
## 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. ## Fix Commit(s) - `ba7be018da354ea9f803ed356d20464df0437916` OpenClaw thanks @allsmog for reporting.
