npm install openclaw@2026.2.15
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-27008, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of Openclaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.2.15), your application is affected.

Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Source Advisory Statement

## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.2.14` - Fixed in: planned release `2026.2.15` ## Impact 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. ## Fix Commit(s) - 2363e1b08 fix(security): restrict skill download target paths - b6305e972 test(skills): split installer security coverage ## Acknowledgement Thanks @Adam55A-code for reporting.
