OpenClaw host-env blocklist missing `GIT_TEMPLATE_DIR` and `AWS_CONFIG_FILE` allows code execution via env override

Summary

Host execution env sanitization did not block GIT_TEMPLATE_DIR or AWS_CONFIG_FILE, even though both can redirect trusted tooling to attacker-controlled content.

Impact

An approved exec request could redirect git or AWS CLI behavior through attacker-controlled configuration and execute untrusted code or load attacker-selected credentials.

Affected Component

src/infra/host-env-security-policy.json, src/infra/host-env-security.ts

Fixed Versions

• Patched: >= 2026.3.28
