AI Summary

This release introduces a new `triage_cve` orchestrator for concurrent CVE analysis alongside security hardening measures and new data sources. It adds deep scanning capabilities with SSVC v2 decision making and ensures CISA KEV entries are always rated CRITICAL.

Key Highlights

  • New `triage_cve` orchestrator that fans out checks across NVD, EPSS, CISA KEV, and PoC discovery concurrently.
  • Deep scanning mode with SSVC v2 gated decision making (Act/Attend/Track).
  • CISA KEV hard override ensuring listed CVEs are always rated CRITICAL.
  • Security hardening including SSRF defense and removal of sampling handlers.
  • Integration of new data sources: VulnCheck NVD++, CIRCL hashlookup, and HIBP Pwned Passwords.

New Features

  • triage_cve orchestrator with quick/standard/deep depth options.
  • VulnCheck NVD++ fallback for NIST NVD unreachability.
  • CIRCL hashlookup integration for known-good allowlists.
  • HIBP Pwned Passwords range API integration.
  • New MCP resources for KEV catalog, EPSS scores, and manifest hash.
  • New MCP prompts for patch decision, comparison, and triage.
  • Streamable-HTTP transport support via MCP_TRANSPORT=http.
  • SSRF defense using scheme allowlist and resolve-then-validate.
  • Centralized Pydantic SecretStr for secrets management.
  • SQLite WAL pragmas for improved concurrent read performance.

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.
