How do I fix GHSA-x82f-27x3-q89c?

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.

How do I detect GHSA-x82f-27x3-q89c in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-x82f-27x3-q89c 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-x82f-27x3-q89c?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-x82f-27x3-q89c can be triaged on real exposure rather than presence alone.

Is GHSA-x82f-27x3-q89c actively exploited in the wild?

No public exploit code has been indexed for GHSA-x82f-27x3-q89c 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

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.
