## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Cyber Vulnerability Intelligence Hub 🛡️

**CVE intelligence from four authoritative open sources in one Actor — CISA KEV (what's actively exploited), NVD (full CVE detail + CVSS), OSV.dev (open-source package vulnerabilities) and EPSS (probability of exploitation). Look up CVEs, search, track known-exploited threats, or scan a dependency. No API key.**

Vulnerability data is scattered across NVD, CISA, EPSS and package advisory databases. This Actor fuses them into one clean, structured feed — so for any CVE you instantly see its severity, whether it's being **actively exploited**, how **likely** it is to be exploited, and whether ransomware crews are using it.

***

### Five modes

| Mode | What it does |
|---|---|
| **lookup** | Give one or more CVE IDs → fused **NVD detail + CVSS + CWE + CISA KEV status + EPSS score**. |
| **search** | Search **NVD** by keyword, CVSS severity, CPE or publish date — each result enriched with KEV + EPSS. |
| **kev** | The **CISA Known Exploited Vulnerabilities** catalog — filter by vendor, product, ransomware use or date. The "patch these now" list. |
| **package** | Give a package + ecosystem (npm, PyPI, Go, Maven…) → the vulnerabilities affecting it, from **OSV.dev** (includes GitHub advisories). |
| **digest** | One summary row over the KEV catalog: top vendors/products, ransomware-linked count, newest additions, highest-EPSS threats. |

### What you get per vulnerability

| Field | Example |
|---|---|
| `cve_id` | CVE-2021-44228 (Log4Shell) |
| `cvss_score` · `cvss_severity` · `cvss_vector` | 10.0 · CRITICAL · CVSS:3.1/AV:N/… |
| `known_exploited` · `kev_date_added` · `kev_due_date` | true · 2021-12-10 · 2021-12-24 |
| `ransomware_use` | Known |
| `epss_score` · `epss_percentile` | 0.99999 · 1.0 *(near-certain exploitation)* |
| `cwes` | CWE-20, CWE-917 |
| `reference_urls` · `nvd_url` | … |

### Examples

**Look up Log4Shell + Heartbleed, fully enriched**

```json
{ "mode": "lookup", "cves": ["CVE-2021-44228", "CVE-2014-0160"] }
```

**All CRITICAL Fortinet CVEs**

```json
{ "mode": "search", "keyword": "Fortinet", "severity": "CRITICAL" }
```

**Everything ransomware crews are actively exploiting**

```json
{ "mode": "kev", "ransomwareOnly": true }
```

**Scan an npm package for known vulnerabilities**

```json
{ "mode": "package", "package": "lodash", "ecosystem": "npm" }
```

### Run it on a schedule

Schedule a daily `kev` or `digest` run to track newly-exploited vulnerabilities the moment CISA adds them, feed a patch-prioritisation workflow, or monitor your dependencies with `package` mode.

### Data sources & notes

- **CISA KEV** — [Known Exploited Vulnerabilities catalog](https://www.cisa.gov/known-exploited-vulnerabilities-catalog) (US CISA), public JSON feed.
- **NVD** — [NIST National Vulnerability Database](https://nvd.nist.gov) CVE API. Public and keyless, but **rate-limited** (~5 requests / 30s) — the Actor throttles automatically, so large `lookup` lists run slowly; `search` returns many CVEs in one request.
- **OSV.dev** — [Open Source Vulnerabilities](https://osv.dev) (Google), covering npm, PyPI, Go, Maven, crates.io, RubyGems, NuGet and more, including GitHub Security Advisories.
- **EPSS** — [Exploit Prediction Scoring System](https://www.first.org/epss/) (FIRST.org): probability (0–1) a CVE will be exploited in the next 30 days.
- All data is public, non-personal vulnerability intelligence. **No API key required.**

# Actor input Schema

## `mode` (type: `string`):

lookup = fused detail for CVE IDs. search = search NVD. kev = CISA Known Exploited catalog. package = vulns for a package (OSV). digest = one summary row.

## `cve` (type: `string`):

A single CVE to look up, e.g. "CVE-2021-44228".

## `cves` (type: `array`):

Multiple CVE IDs to look up, e.g. \["CVE-2021-44228", "CVE-2014-0160"]. NVD is rate-limited (no key), so large lists run slowly.

## `keyword` (type: `string`):

Free-text to search for, e.g. "Microsoft SharePoint", "remote code execution", "Fortinet".

## `severity` (type: `string`):

Only CVEs of this CVSS v3 severity.

## `cpe` (type: `string`):

Restrict to a product CPE, e.g. "cpe:2.3:o:microsoft:windows\_10".

## `pubStartDate` (type: `string`):

Only CVEs published on/after this date (YYYY-MM-DD). NVD requires a range ≤ 120 days; pair with 'Published before'.

## `pubEndDate` (type: `string`):

Only CVEs published on/before this date (YYYY-MM-DD).

## `vendor` (type: `string`):

Filter the KEV catalog by vendor, e.g. "Microsoft", "Cisco", "Fortinet".

## `product` (type: `string`):

Filter the KEV catalog by product, e.g. "Exchange", "iOS".

## `ransomwareOnly` (type: `boolean`):

Only KEV entries known to be used in ransomware campaigns.

## `addedAfter` (type: `string`):

Only KEV entries added on/after this date (YYYY-MM-DD).

## `package` (type: `string`):

Package to scan, e.g. "lodash", "log4j-core", "django".

## `ecosystem` (type: `string`):

Package ecosystem (OSV names): npm, PyPI, Go, Maven, crates.io, RubyGems, NuGet, Packagist, Pub, Hex.

## `version` (type: `string`):

Only vulns affecting this exact version, e.g. "4.17.20". Leave blank for all known vulns of the package.

## `includeEpss` (type: `boolean`):

Enrich each CVE with its EPSS exploitation-probability score and percentile.

## `maxResults` (type: `integer`):

Cap on rows returned.

## Actor input object example

```json
{
  "mode": "lookup",
  "cve": "CVE-2021-44228",
  "severity": "",
  "ransomwareOnly": false,
  "includeEpss": true,

apify call straightforward_hydra/cyber-vuln-intelligence --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,straightforward_hydra/cyber-vuln-intelligence"

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
