• CVE-2026-32022: 0.27% estimated exploitation activity in the next 30 days; percentile 19.15 (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 OpenClaw tools.exec.safeBins had a stdin-only policy bypass for grep. If pattern input was supplied through -e / --regexp, the validator consumed the pattern as a flag value and still allowed one positional operand. That positional could be a bare filename like .env. Affected Packages / Versions - Package: openclaw (npm) - Latest published vulnerable version: 2026.2.19-2 - Structured vulnerable range: <= 2026.2.19-2 - Planned fixed range for next release: = 2026.2.21 Exploit Preconditions - tools.exec.safeBins must include grep (this is opt-in; grep is not in the default safe-bin list). - An actor must be able to invoke exec tooling under that profile. Technical Details src/infra/exec-safe-bin-policy.ts configured grep with maxPositional: 1 and allowed -e / --regexp value flags. Because -e consumes the pattern in flag-value position, the remaining positional budget could be used for a file operand. Example accepted input in vulnerable builds: That violated the intended…

# Patch Next advisory brief: CVE-2026-32022

Advisory: OpenClaw safeBins grep -e File Read Bypass (stdin-only policy bypass)
IDs: CVE-2026-32022, GHSA-3xfw-4pmr-4xc5
Record: https://patchnext.com/advisories/cve-2026-32022 (revision 3, source checked 26 Oct 2026, 12:53 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.21. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.2.21; fixed in 2026.2.21

## 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.
