Sam Valladares a92fb2b6ed release: v1.1.3 — security hardening, edition 2024, dependency updates
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

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:

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)

Security Checklist

  • No hardcoded secrets
  • Parameterized SQL queries
  • Input validation on all tools
  • No command injection vectors
  • No unsafe Rust code
  • Dependencies audited
