Security: - Fix RUSTSEC-2026-0007 (bytes integer overflow) - Restrict SQLite database file permissions to 0600 on Unix - Add 100KB size limit to intention descriptions (DoS prevention) - Redact JSON-RPC payloads from debug logs (data leakage prevention) - Update SECURITY.md with encryption docs and supported versions Modernization: - Upgrade Rust edition 2021 → 2024, MSRV 1.75 → 1.85 - Upgrade actions/checkout@v4 → v5, codecov/codecov-action@v3 → v5 - Update all dependencies to latest compatible versions - Fix edition 2024 match ergonomics in compression.rs Clippy fixes: - Rename from_str → parse_name to avoid shadowing FromStr trait - Replace .max().min() with .clamp() - Replace sort_by with sort_by_key Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

## Reporting a Vulnerability
|
|
|
|
If you discover a security vulnerability in Vestige, please report it responsibly:
|
|
|
|
1. **DO NOT** open a public GitHub issue
|
|
2. Email the maintainer directly (see GitHub profile)
|
|
3. Include:
|
|
- Description of the vulnerability
|
|
- Steps to reproduce
|
|
- Potential impact
|
|
- Suggested fix (if any)
|
|
|
|
You can expect a response within 48 hours.
|
|
|
|
## Security Model
|
|
|
|
### Trust Boundaries
|
|
|
|
Vestige is a **local MCP server** designed to run on your machine with your user permissions:
|
|
|
|
- **Trusted**: The MCP client (Claude Code/Desktop) that connects via stdio
|
|
- **Untrusted**: Content passed through MCP tool arguments (validated before use)
|
|
|
|
### What Vestige Does NOT Do
|
|
|
|
- ❌ Make network requests (except first-run model download from Hugging Face)
|
|
- ❌ Execute shell commands
|
|
- ❌ Access files outside its data directory
|
|
- ❌ Send telemetry or analytics
|
|
- ❌ Phone home to any server
|
|
|
|
### Data Storage
|
|
|
|
All data is stored locally in SQLite:
|
|
|
|
| Platform | Location |
|
|
|----------|----------|
|
|
| macOS | `~/Library/Application Support/com.vestige.core/vestige.db` |
|
|
| Linux | `~/.local/share/vestige/core/vestige.db` |
|
|
| Windows | `%APPDATA%\vestige\core\vestige.db` |
|
|
|
|
**Default**: Data is stored in plaintext with owner-only file permissions (0600).
|
|
|
|
### Encryption at Rest
|
|
|
|
For database-level encryption, build with SQLCipher:
|
|
```bash
|
|
cargo build --no-default-features --features encryption,embeddings,vector-search
|
|
```
|
|
Set `VESTIGE_ENCRYPTION_KEY` environment variable. SQLCipher encrypts all database files including the WAL journal. Alternatively, use OS-level encryption (FileVault, BitLocker, LUKS).
|
|
|
|
### Input Validation
|
|
|
|
All MCP tool inputs are validated:
|
|
|
|
- Content size limit: 1MB max
|
|
- Query length limit: 1000 characters
|
|
- FTS5 queries are sanitized to prevent injection
|
|
- All SQL uses parameterized queries (`params![]` macro)
|
|
|
|
### Dependencies
|
|
|
|
We use well-maintained dependencies and run `cargo audit` regularly. Current status:
|
|
|
|
- **Vulnerabilities**: 0
|
|
- **Warnings**: 2 (unmaintained transitive dependencies with no known CVEs)
|
|
|
|
