No CVSS score has been assigned to GHSA-jfv4-h8mc-jcp8 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-jfv4-h8mc-jcp8?

GHSA-jfv4-h8mc-jcp8 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix GHSA-jfv4-h8mc-jcp8?

Update openclaw to 2026.2.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jfv4-h8mc-jcp8 is resolved across your whole dependency graph.

How do I detect GHSA-jfv4-h8mc-jcp8 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-jfv4-h8mc-jcp8 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-jfv4-h8mc-jcp8?

O3 pinpoints whether GHSA-jfv4-h8mc-jcp8 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-jfv4-h8mc-jcp8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-jfv4-h8mc-jcp8 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-jfv4-h8mc-jcp8?

GHSA-jfv4-h8mc-jcp8 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 21th 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-jfv4-h8mc-jcp8?

GHSA-jfv4-h8mc-jcp8 is classified as CWE-283 (CWE-283). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-jfv4-h8mc-jcp8 published, and has it been updated?

GHSA-jfv4-h8mc-jcp8 was published on February 18, 2026 and was last updated on February 23, 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

OpenClaw CLI process cleanup used system-wide process enumeration and pattern matching to terminate processes without verifying they were owned by the current OpenClaw process. On shared hosts, unrelated processes could be terminated if they matched the pattern.

Affected Packages / Versions

Package: openclaw (npm)
Affected: < 2026.2.14 (including the latest published version 2026.2.13)
Fixed: 2026.2.14 (planned next release)

Details

The CLI runner cleanup helpers could kill processes matched by command-line patterns without validating process ownership.

Fix

Process cleanup is now scoped to owned processes only by filtering to direct child PIDs of the current process (ppid == process.pid) before sending signals.

Hardening follow-ups:

Prefer graceful termination for resume cleanup (SIGTERM, then SIGKILL fallback).
Reduce false negatives from ps argv truncation by preferring wide output (ps -axww) with a fallback.
Tighten command-line token matching to avoid substring matches.

Release Process Note

This advisory is pre-set with patched version 2026.2.14. After 2026.2.14 is published to npm, the remaining step should be to publish this advisory.
