Which packages are affected by GHSA-7fcc-cw49-xm78?

GHSA-7fcc-cw49-xm78 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix GHSA-7fcc-cw49-xm78?

Update openclaw to 2026.2.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7fcc-cw49-xm78 is resolved across your whole dependency graph.

How do I detect GHSA-7fcc-cw49-xm78 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-7fcc-cw49-xm78 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-7fcc-cw49-xm78?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-7fcc-cw49-xm78 can be triaged on real exposure rather than presence alone.

Is GHSA-7fcc-cw49-xm78 actively exploited in the wild?

No public exploit code has been indexed for GHSA-7fcc-cw49-xm78 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-7fcc-cw49-xm78?

GHSA-7fcc-cw49-xm78 has an EPSS (Exploit Prediction Scoring System) score of 1.1%, placing it in the 63th 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-7fcc-cw49-xm78?

GHSA-7fcc-cw49-xm78 is classified as OS Command Injection (CWE-78). This weakness type 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-7fcc-cw49-xm78 published, and has it been updated?

GHSA-7fcc-cw49-xm78 was published on March 3, 2026 and was last updated on March 19, 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

The Lobster extension tool execution path used a Windows shell fallback (shell: true) after spawn failures (EINVAL/ENOENT). In that fallback path, shell metacharacters in command arguments can be interpreted by the shell, enabling command injection.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.2.17
Latest confirmed affected published version: 2026.2.17
Patched version: 2026.2.19

Technical Details

In affected releases (including v2026.2.17), extensions/lobster/src/lobster-tool.ts retried subprocess launch with shell: true on Windows for EINVAL/ENOENT spawn errors. The fix removes shell fallback and resolves Windows wrappers to explicit executable/script argv execution.
