OpenClaw: Sandboxed agents could escape exec routing via host=node override
Summary
Sandboxed agents could escape exec routing via host=node override.
Affected Packages / Versions
- Package:
openclaw - Ecosystem: npm
- Affected versions:
>= 2026.4.5 < 2026.4.10 - Patched versions:

Impact
A sandboxed agent could request host: "node" and route exec to a remote node instead of the intended sandbox execution path, bypassing the sandbox routing boundary.
Technical Details
The fix blocks sandboxed exec escape to remote node targets and keeps routing aligned with the active sandbox policy.
Fix
The issue was fixed in #63880. The first stable tag containing the fix is v2026.4.10, and openclaw@2026.4.14 includes the fix.
