OpenClaw: OpenShell `mirror` mode can convert untrusted sandbox files into explicitly enabled workspace hooks and execute them on the host during gateway startup
Summary
OpenShell mirror mode can convert untrusted sandbox files into explicitly enabled workspace hooks and execute them on the host during gateway startup
Current Maintainer Triage
- Status: narrow
- Normalized severity: medium
- Assessment: Real on shipped <=2026.3.22 OpenShell mirror sync, but exploit needs mirror mode plus hooks enabled plus explicit hook opt-in plus restart, so high is overstated even though the direct fix shipped in v2026.3.28.
