v0.2.0

atlasia-ma/MoulSotv0.2.0Jun 22, 2026by mukul975

AI Summary

This release introduces a new `triage_cve` orchestrator for concurrent vulnerability assessment and significant security hardening measures. It expands data sources, improves scoring logic with CISA KEV overrides and SSVC v2 support, and enhances MCP capabilities.

Key Highlights

  • New `triage_cve` orchestrator for concurrent analysis of NVD, EPSS, CISA KEV, and PoC discovery
  • CISA KEV hard override to ensure CRITICAL severity for listed CVEs
  • Security hardening including SSRF defense and removal of sampling handlers
  • New MCP resources and prompts for vulnerability management workflows
  • Support for deep scanning with SSVC v2 decision gating

New Features

  • Additive `triage_cve` orchestrator with depth levels (quick, standard, deep)
  • VulnCheck NVD++ fallback and new data sources (CIRCL hashlookup, HIBP Pwned Passwords)
  • Streamable-HTTP transport support via `MCP_TRANSPORT=http`
  • New MCP resources (kev://, epss://, manifest://) and prompts (patch_decision, compare_and_prioritize)
  • Security enhancements: SSRF defense, Pydantic SecretStr, removal of sampling handler
  • SQLite WAL pragmas for concurrent reads and multi-stage non-root Dockerfile

Full Release Notes

## CVE MCP Server v0.2.0

A major feature release. **Additive** — all existing tools remain registered; the new `triage_cve` orchestrator is the recommended entry point.

### ⭐ Orchestration
- **`triage_cve`** — one tool call fans out NVD + EPSS + CISA KEV (+ public PoC discovery) concurrently, computes the composite risk score, and returns a clean report. `depth` = `quick` / `standard` / `deep`; **`deep`** also emits an SSVC v2 gated decision (CISA Deployer model → `Act` / `Attend` / `Track*` / `Track`).
- Transparent **VulnCheck NVD++ fallback** used automatically when NIST NVD is unreachable or throttled.

### 🎯 Scoring
- **CISA KEV hard override** — a KEV-listed CVE is always **CRITICAL** (score clamped ≥ 76), regardless of CVSS/EPSS.
- **`scoring_version`** stamped into `triage_cve`, `calculate_risk_score`, and `health_check`.
- CVSS reframed as a **severity** signal (not exploitation-likelihood), per Allodi & Massacci 2014.

### 🔌 New data sources
- **VulnCheck NVD++** (NVD-schema fallback), **CIRCL hashlookup** (known-good allowlist), **HIBP Pwned Passwords** range API (keyless k-anonymity).

### 🧩 MCP enhancements
- **Resources**: `kev://catalog`, `epss://scores/{cve_id}`, `manifest://tool-hash` (SHA-256 over the registered tool surface).
- **Prompts**: `patch_decision`, `compare_and_prioritize`, `dependency_triage`.
- **Streamable-HTTP transport** via `MCP_TRANSPORT=http` (stdio remains the default).
- Expanded `health_check` (scoring version, manifest hash, configured-key status).

### 🔐 Security hardening
- Server **never** registers a sampling handler / never issues `sampling/createMessage` (Unit 42 MCP-sampling attack vector).
- **SSRF** defense: scheme allowlist + resolve-then-validate (rejects private/reserved IPs).
- Secrets centralized as Pydantic `SecretStr`.

### 🏗️ Infrastructure
- Multi-stage non-root **Dockerfile** + `.dockerignore`.
- SQLite **WAL** pragmas for concurrent reads; null-object rate limiter; fixed-interval deterministic retry; async fan-out helper; static Admiralty source-trust table.

**Verified:** ruff clean, 30/30 tests passing.
