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

OpenClaw: SSH-based sandbox backends pass unsanitized process.env to child processes
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.
