OpenClaw has a workspace-only sandbox guard mismatch for @-prefixed absolute paths

CVE-2026-32033GHSA-27cr-4p5m-74rj

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (openclaw 2026.2.24), 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.

A workspace-only file-system guard mismatch allowed @-prefixed absolute paths to bypass boundary validation in some tool path checks. Impact When tools.fs.workspaceOnly=true, certain @-prefixed absolute paths (for example @/etc/passwd) could be validated before canonicalization while runtime path handling normalized the prefix differently. In affected code paths this could permit reads outside the intended workspace boundary. Per SECURITY.md, OpenClaw is primarily a personal-assistant runtime with trusted-user assumptions, and this path is gated behind non-default sandbox/tooling configuration. That reduces practical exposure, but the bypass is still a security bug and is fixed.

# Patch Next advisory brief: CVE-2026-32033

Advisory: OpenClaw has a workspace-only sandbox guard mismatch for @-prefixed absolute paths
IDs: CVE-2026-32033, GHSA-27cr-4p5m-74rj
Record: https://patchnext.com/advisories/cve-2026-32033 (revision 3, source checked 26 Oct 2026, 12:46 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.24. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected <= 2026.2.23; fixed in 2026.2.24

## 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-27cr-4p5m-74rj (OSV record GHSA-27cr-4p5m-74rj lists affected ranges: npm openclaw >=0 <2026.2.24 (fixed))
- Verified: https://github.com/advisories/GHSA-27cr-4p5m-74rj (GitHub-reviewed advisory GHSA-27cr-4p5m-74rj lists affected ranges: npm openclaw >=0 <=2026.2.23)
