Which packages are affected by CVE-2026-31992?

CVE-2026-31992 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-31992?

Update openclaw to 2026.2.23 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-31992 is resolved across your whole dependency graph.

How do I detect CVE-2026-31992 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-2026-31992 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-2026-31992 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-31992 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-2026-31992?

CVE-2026-31992 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 28th 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-2026-31992?

CVE-2026-31992 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.

When was CVE-2026-31992 published, and has it been updated?

CVE-2026-31992 was published on March 19, 2026 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

In allowlist mode, system.run guardrails could be bypassed through env -S, causing policy-analysis/runtime-execution mismatch for shell wrapper payloads.

Severity Rationale (Medium)

This issue is rated medium because it is a guardrail/policy bypass in OpenClaw's trusted-operator model, not an authentication boundary break.

Authenticated Gateway callers are trusted operators by design.
exec approvals/allowlists are operator safety controls.
The bug still weakens expected safety behavior and can enable unintended command execution when untrusted content influences tool input.

Affected Packages / Versions

Package: openclaw (npm)
Vulnerable versions: <= 2026.2.22-2
Patched versions: >= 2026.2.23

Latest published npm version checked during triage: 2026.2.22-2.

Technical Impact

When /usr/bin/env is allowlisted, env -S 'sh -c ...' could be treated as allowed non-wrapper argv while runtime still executes shell-wrapper semantics.

Fix Commit(s)

a1c4bf07c6baad3ef87a0e710fe9aef127b1f606 (core allowlist/runtime parity hardening)

Release Process Note

patched_versions is pre-set to >= 2026.2.23, so this advisory is now public.
