OpenClaw: Sandboxed agents could escape exec routing via host=node override
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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: `>= 2026.4.10`
## 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 `[email protected]` includes the fix.

## Release Process Note
