openclawnpmDescription
Summary
OpenShell FS bridge writes stay pinned to the sandbox mount root
Affected Packages / Versions
- Package: openclaw (npm)
- Affected versions: <= 2026.4.21
- Fixed version: 2026.4.22
Impact
A time-of-check/time-of-use race around OpenShell sandbox filesystem writes could let a symlink swap redirect a write outside the intended local mount root.
Fix
OpenShell write paths now validate the canonical target against the mount root, reject unsafe symlink parents and symlink leaves for writes, and use root-scoped write helpers before syncing to the remote sandbox.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update openclaw to 2026.4.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wppj-c6mr-83jj is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-wppj-c6mr-83jj is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-wppj-c6mr-83jj. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-wppj-c6mr-83jj in your dependencies?
O3 detects GHSA-wppj-c6mr-83jj across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
