CVE-2026-41357 — OpenClaw < 2026.3.31 - Unsanitized Environment Variable Leakage in SSH Sandbox Backends

Affected: OpenClaw

OpenClaw before 2026.3.31 contains an environment variable leakage vulnerability in SSH-based sandbox backends that pass unsanitized process.env to child processes. Attackers can exploit this by leveraging non-default SSH environment forwarding configurations to leak sensitive environment variables from parent processes to SSH child processes.

GHSA-j9pv-rrcj-6pfx — OpenClaw: SSH-based sandbox backends pass unsanitized process.env to child processes

Affected: npm: openclaw

## Summary SSH-based sandbox backends pass unsanitized process.env to child processes

## Current Maintainer Triage - Status: narrow - Normalized severity: low - Assessment: Shipped SSH sandbox paths leaked unsanitized env into local SSH child processes, but remote leakage needs non-default SSH env forwarding, so lower to low.

## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31`

## Fix Commit(s) - `cfe14459531e002a1c61c27d97ec7dc8aecddc1f` — 2026-03-30T20:05:57+01:00
