# CISA KEV Feed: Known Exploited Vulnerabilities API | Johto Data (`johto.data/exploited-vuln-feed`) Actor

CISA Known Exploited Vulnerabilities (KEV) catalog as clean rows: vendor, product, date added, federal due date, days until due, required action, ransomware flag, CWEs. Filter by vendor, product, CVE, keyword or date. $9 per 1,000 CVEs.

## Pricing

Pay per event

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## CISA KEV Feed: Known Exploited Vulnerabilities API

By Johto Data. One row per CISA Known Exploited Vulnerabilities (KEV) entry, newest first.

### For AI agents

- **Call:** `{}` returns the 10 newest KEV additions. Examples: `{"vendors":["Fortinet"],"maxItems":5}` · `{"addedSince":"2026-10-01","ransomwareOnly":true}` · `{"cveIds":["CVE-2021-44228"]}`.
- **Returns:** vendor, product, date added, federal due date, `daysUntilDue`, `overdue`, required action, ransomware use, CWEs.
- **Aliases:** `keywordSearch`, `cveId`, `maxResults`.
- **Not included:** CVSS, EPSS, CPE and other non-KEV data.

| | This Actor | Leading alternative |
|---|---|---|
| Per CVE row | $0.0009 | $0.0018 |
| Run start | $0.0001 | none |
| Measured run time | 10 rows: 2.6 s | not measured |

Sample (run 7KfH8bIE0yXZ6dgxF, Oct 22 2026):

| cveId | vendor | product | kevDateAdded | kevDueDate | knownRansomware |
|---|---|---|---|---|---|
| CVE-2026-96656 | Plex | Media Server | 2026-10-20 | 2026-10-23 | false |
| CVE-2026-96655 | Plex | Media Server | 2026-10-20 | 2026-11-03 | false |
| CVE-2026-96654 | Plex | Media Server | 2026-10-20 | 2026-10-23 | false |

### Output schema

| Field | Meaning |
|---|---|
| `cveId`, `vendor`, `product`, `vulnName`, `shortDescription` | Identity |
| `isKev`, `kevDateAdded`, `kevDueDate`, `daysUntilDue`, `overdue` | KEV status and BOD 22-01 due date |
| `requiredAction`, `knownRansomware`, `knownRansomwareCampaignUse`, `kevNotes` | What to do; ransomware use |
| `cwe[]` | CWEs listed by CISA |
| `kevCatalogVersion`, `kevCatalogReleased`, `source`, `sourceUrl`, `checkedAt` | Provenance |

### Inputs

`addedSince`, `ransomwareOnly`, `vendors[]`, `products[]`, `cveIds[]`, `keyword`, `cweId`, `maxItems` (default 10, max 2,000). Each run reads the current CISA KEV JSON catalog in one request.

### Cheap first run

`{"maxItems": 5}` costs $0.0046 (5 × $0.0009 + $0.0001). 1,000 CVEs cost $0.90.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("johto.data/exploited-vuln-feed").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("johto.data/exploited-vuln-feed").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call johto.data/exploited-vuln-feed --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,johto.data/exploited-vuln-feed"
        }
    }
}
```

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).
