• CVE-2026-27487: 1.37% estimated exploitation activity in the next 30 days; percentile 71.91 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary On macOS, the Claude CLI keychain credential refresh path constructed a shell command to write the updated JSON blob into Keychain via security add-generic-password -w .... Because OAuth tokens are user-controlled data, this created an OS command injection risk. The fix avoids invoking a shell by using execFileSync("security", argv) and passing the updated keychain payload as a literal argument.

# Patch Next advisory brief: CVE-2026-27487

Advisory: OpenClaw: Prevent shell injection in macOS keychain credential write
IDs: CVE-2026-27487, GHSA-4564-pvr2-qq4h
Record: https://patchnext.com/advisories/cve-2026-27487 (revision 2, source checked 26 Oct 2026, 12:42 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.14. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.2.14; fixed in 2026.2.14

## 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-4564-pvr2-qq4h (OSV record GHSA-4564-pvr2-qq4h lists affected ranges: npm openclaw >=0 <2026.2.14 (fixed))
