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: `>= 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 `openclaw@2026.4.14` includes the fix. ## Fix Commit(s) - `dffad08529202edbf34e4808788e1182fe10f6a9` - PR: #63880 ## Release Process Note Users should upgrade to `openclaw` 2026.4.10 or newer. The latest npm release, `2026.4.14`, already includes the fix. ## Credits Thanks to @zsxsoft, with sponsorship from @KeenSecurityLab and @qclawer for reporting this issue.
