CVE-2026-42434 — OpenClaw 2026.4.5 < 2026.4.10 - Sandbox Escape via host Parameter Override in Exec Routing

Affected: OpenClaw

OpenClaw versions 2026.4.5 before 2026.4.10 contain a sandbox escape vulnerability allowing sandboxed agents to override exec routing by specifying host=node. Attackers can bypass sandbox boundaries and route execution to remote nodes instead of intended sandbox paths.

GHSA-736r-jwj6-4w23 — OpenClaw: Sandboxed agents could escape exec routing via host=node override

Affected: npm: openclaw

## Summary

Sandboxed agents could escape exec routing via host=node override.

## Affected Packages / 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.
