BREW-OPENCLAW-CLI-CVE-20… (GHSA-736R-JWJ6-4W23)

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-20 10:38 – Source website

Summary

OpenClaw: Sandboxed agents could escape exec routing via host=node override

Details

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.

Vulnerability from github – Published: 2026-04-17 22:14 – Updated: 2026-05-08 01:32

Summary

OpenClaw: Sandboxed agents could escape exec routing via host=node override

Details

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.
