Affected: Homebrew: openclaw-cli

## 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`

OpenClaw thanks @AntAISecurityLab for reporting.

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.
