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-rm5c-4rmf-vvhw 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-rm5c-4rmf-vvhw?

O3 pinpoints whether GHSA-rm5c-4rmf-vvhw 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-rm5c-4rmf-vvhw actively exploited in the wild?

No public exploit code has been indexed for GHSA-rm5c-4rmf-vvhw 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

Sandbox file operations use check-then-act, bypassing fd-based TOCTOU defenses

Current Maintainer Triage

Status: narrow
Normalized severity: medium
Assessment: Released workspace-only apply_patch remove and mkdir operations were still check-then-act, but the draft overstates scope by bundling broader edit paths; keep it open but narrow it to the actual sandbox-workspace mutation boundary.
