Which packages are affected by GHSA-82g8-464f-2mv7?

GHSA-82g8-464f-2mv7 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix GHSA-82g8-464f-2mv7?

Update openclaw to 2026.2.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-82g8-464f-2mv7 is resolved across your whole dependency graph.

How do I detect GHSA-82g8-464f-2mv7 in my npm dependencies?

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.

How do I mitigate GHSA-82g8-464f-2mv7 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-82g8-464f-2mv7?

O3 pinpoints whether GHSA-82g8-464f-2mv7 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-82g8-464f-2mv7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-82g8-464f-2mv7 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-82g8-464f-2mv7?

GHSA-82g8-464f-2mv7 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 23th 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-82g8-464f-2mv7?

GHSA-82g8-464f-2mv7 is classified as CWE-74 (CWE-74), Code Injection (CWE-94). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-82g8-464f-2mv7 published, and has it been updated?

GHSA-82g8-464f-2mv7 was published on February 27, 2026 and was last updated on March 14, 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

applySkillConfigEnvOverrides previously copied skills.entries.*.env values into the host process.env without applying the host env safety policy.

Impact

In affected versions, dangerous process-level variables such as NODE_OPTIONS could be injected when unset, which can influence runtime/child-process behavior.

Required attacker capability

An attacker must be able to modify OpenClaw local state/config (for example ~/.openclaw/openclaw.json) to set skills.entries.<skill>.env or related skill config values.

Remediation

Fixed in 2026.2.21 by sanitizing skill env overrides and blocking dangerous host env keys (including NODE_OPTIONS) before applying overrides, with regression tests covering blocked dangerous keys.
