🔒 SECURITY (Future): Explore sandboxed script execution #10
Description
Security Research: Sandboxed Script Execution
Severity: LOW
Priority: LOW (Future)
Category: Advanced Security / Research
Problem
Statusline script executes with full user privileges:
- Can access all user files
- Can make network requests
- Can execute arbitrary commands
- No privilege separation
Impact
- Overly broad permissions
- Large attack surface
- Difficult to audit security boundaries
Potential Solutions
Research and evaluate sandboxing options:
Option 1: Docker/Container
- Run script in minimal container
- Limited filesystem access
- No network by default
- Complexity: HIGH
Option 2: Node.js VM
- Execute in isolated V8 context
- Limited API surface
- May not work for bash scripts
- Complexity: MEDIUM
Option 3: Dedicated User
- Create devflow-statusline user
- Limited permissions
- OS-level isolation
- Complexity: MEDIUM
Option 4: Claude Code Native Support
- Request sandboxing feature from Claude Code team
- Best long-term solution
- Requires upstream changes
- Complexity: N/A (external)
Research Tasks
- Investigate Claude Code's execution model
- Evaluate container-based approaches
- Assess OS-level sandboxing (seccomp, AppArmor)
- Benchmark performance impact
- Document security tradeoffs
- Propose RFC for implementation
Questions
- Does Claude Code support sandboxed command execution?
- What's the performance overhead of each approach?
- How do we balance security vs usability?
- What's the threat model priority?
