How do I fix GHSA-r54r-wmmq-mh84?

Update openclaw to 2026.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r54r-wmmq-mh84 is resolved across your whole dependency graph.

How do I detect GHSA-r54r-wmmq-mh84 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-r54r-wmmq-mh84 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.

Is GHSA-r54r-wmmq-mh84 actively exploited in the wild?

No public exploit code has been indexed for GHSA-r54r-wmmq-mh84 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.

What is the EPSS score for GHSA-r54r-wmmq-mh84?

GHSA-r54r-wmmq-mh84 has an EPSS (Exploit Prediction Scoring System) score of 0.1%, placing it in the 1th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-r54r-wmmq-mh84?

GHSA-r54r-wmmq-mh84 is classified as CWE-367 (CWE-367). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

Summary

ZIP extraction in OpenClaw could be raced into writing outside the intended destination directory via parent-directory symlink rebind between validation and write.

Affected Packages / Versions

Package: openclaw (npm)
Vulnerable versions: <= 2026.3.1
Latest published vulnerable version confirmed: 2026.3.1 (npm as of 2026-03-02)
Patched version: 2026.3.2 (released)

Technical Details

In src/infra/archive.ts, ZIP extraction previously validated output paths, then later opened/truncated the destination path in a separate step. A local race on parent-directory symlink state could redirect the final write outside the extraction root.

The fix hardens ZIP writes by binding writes to the opened file handle identity and avoiding the pre-write truncate race path, with shared fd realpath verification in src/infra/fs-safe.ts and regression coverage in src/infra/archive.test.ts.
