Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-736r-jwj6-4w23 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-736r-jwj6-4w23?

O3 pinpoints whether GHSA-736r-jwj6-4w23 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-736r-jwj6-4w23 actively exploited in the wild?

No public exploit code has been indexed for GHSA-736r-jwj6-4w23 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

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.
