How do I detect CVE-2026-27008 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-2026-27008 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 CVE-2026-27008?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-27008 can be triaged on real exposure rather than presence alone.

Is CVE-2026-27008 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-27008 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-2026-27008?

CVE-2026-27008 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 7th 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-2026-27008?

CVE-2026-27008 is classified as CWE-73 (CWE-73). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

OpenClaw is a personal AI assistant. Prior to version 2026.2.15, a bug in download skill installation allowed targetDir values from skill frontmatter to resolve outside the per-skill tools directory if not strictly validated. In the admin-only skills.install flow, this could write files outside the intended install sandbox. Version 2026.2.15 contains a fix for the issue.
