OpenClaw's TOCTOU symlink race in writeFileWithinRoot could create or truncate files outside root boundaries

openclawnpmDescription
Summary
A symlink-retarget TOCTOU race in writeFileWithinRoot could point an attacker-controlled path alias outside the configured root between resolution and write operations.
Impact
Affected versions could cause out-of-root write side effects (including file creation or truncation) before final boundary validation.
Fix
Root-scoped write flow now opens existing files without pre-truncation, creates missing files with exclusive create semantics, truncates only after post-open identity/boundary checks, and removes out-of-root artifacts when a race is detected.

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 2026.3.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x82f-27x3-q89c 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-x82f-27x3-q89c 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-x82f-27x3-q89c. 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-x82f-27x3-q89c in your dependencies?
O3 detects GHSA-x82f-27x3-q89c across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
