OpenClaw's skills-install-download can be redirected outside the tools root by rebinding the validated base path

CVE-2026-33574GHSA-vhwf-4x96-vqx2

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (openclaw 2026.3.8), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

OpenClaw's skills download installer validated the intended per-skill tools root lexically, but later reused that mutable path while downloading and copying the archive into place. If a local attacker could rebind that tools-root path between validation and the final write, the installer could be redirected to write outside the intended tools directory. The fix pins the canonical per-skill tools root immediately after validation and derives later download/copy paths from that canonical root, so rebinding the lexical path fails closed instead of redirecting the write.

# Patch Next advisory brief: CVE-2026-33574

Advisory: OpenClaw's skills-install-download can be redirected outside the tools root by rebinding the validated base path
IDs: CVE-2026-33574, GHSA-vhwf-4x96-vqx2
Record: https://patchnext.com/advisories/cve-2026-33574 (revision 3, source checked 26 Oct 2026, 12:47 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.3.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected <= 2026.3.7; fixed in 2026.3.8

## Suggested inspection (read-only)
- `npm ls openclaw --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on openclaw.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-vhwf-4x96-vqx2 (OSV record GHSA-vhwf-4x96-vqx2 lists affected ranges: npm openclaw >=0 <2026.3.8 (fixed))
- Verified: https://github.com/advisories/GHSA-vhwf-4x96-vqx2 (GitHub-reviewed advisory GHSA-vhwf-4x96-vqx2 lists affected ranges: npm openclaw >=0 <=2026.3.7)
