Which packages are affected by CVE-2026-31993?

CVE-2026-31993 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-31993?

Update openclaw to 2026.2.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-31993 is resolved across your whole dependency graph.

How do I detect CVE-2026-31993 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 CVE-2026-31993 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 CVE-2026-31993 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-31993 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 CVE-2026-31993?

CVE-2026-31993 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 24th 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 CVE-2026-31993?

CVE-2026-31993 is classified as CWE-184 (CWE-184). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

Summary

In the macOS companion app (currently beta), a parsing mismatch in exec approvals could let shell-chain payloads pass allowlist checks in system.run under specific settings.

Impact

This path requires all of the following:

authenticated caller with operator.write
paired macOS beta node host
exec approvals set to security=allowlist and ask=on-miss

Under those conditions, a shell-chain command could be approved from an incomplete command view and then executed on the paired macOS host.

Default Install Status

Default installs are not affected.

Affected Packages / Versions

Package: openclaw (npm)
Affected: <= 2026.2.21-2
Patched (planned next release): >= 2026.2.22

Technical Details

The fix hardens macOS allowlist resolution by evaluating shell chains per segment and failing closed on unsafe shell-substitution parsing in allowlist mode.

Product Status Note

The affected macOS companion app path is currently in beta.

Release Process Note

patched_versions is pre-set to the planned next npm release (2026.2.22) so once that version is published, this advisory can be published without additional metadata edits.
