CVE-2026-31995

Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, sich erhöhte Berechtigungen zu verschaffen, Daten zu manipulieren, einen Denial-of-Service-Zustand auszulösen, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen oder andere nicht näher spezifizierte Angriffe durchzuführen.

### 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.
