OpenClaw has Inconsistent Host Exec Environment Override Sanitization

CVE-2026-35650GHSA-39pp-xp36-q6mg

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (openclaw 2026.3.22), 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.

Summary Gateway host exec env override handling did not consistently apply the shared host environment policy, so blocked or malformed override keys could slip through inconsistent sanitization paths. Affected Packages / Versions - Package: openclaw (npm) - Affected: < 2026.3.22 - Fixed: = 2026.3.22 - Latest released tag checked: v2026.3.23-2 (630f1479c44f78484dfa21bb407cbe6f171dac87) - Latest published npm version checked: 2026.3.23-2 Fix Commit(s) - 7abfff756d6c68d17e21d1657bbacbaec86de232 Release Status The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2. Code-Level Confirmation - src/infra/host-env-security.ts now provides one shared sanitizer and fail-closed diagnostics for blocked or malformed override keys. - src/agents/bash-tools.exec.ts and src/node-host/invoke-system-run.ts both route env overrides through the shared sanitizer before execution. OpenClaw thanks @zpbrent for reporting.

# Patch Next advisory brief: CVE-2026-35650

Advisory: OpenClaw has Inconsistent Host Exec Environment Override Sanitization
IDs: CVE-2026-35650, GHSA-39pp-xp36-q6mg
Record: https://patchnext.com/advisories/cve-2026-35650 (revision 3, source checked 26 Oct 2026, 12:48 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.3.22. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.3.22; fixed in 2026.3.22

## 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-39pp-xp36-q6mg (OSV record GHSA-39pp-xp36-q6mg lists affected ranges: npm openclaw >=0 <2026.3.22 (fixed))
