> [!IMPORTANT]

> The OpenCVE v1 development is freezed as the v2 will be released soon.

Apart from using other technologies (Django & Airflow), this new version will provide new features like organizations & projects, advanced notifications or usage of multiple CVEs providers to cross the information (CVSS, CPEs, References...).

For more information, included what will change and some ETAs, you can read [this blog post](https://blog.opencve.io/posts/opencve-v2-is-coming-soon/).

Try **for free** OpenCVE on [https://www.opencve.io](https://www.opencve.io) or check [documentation](https://docs.opencve.io) to install it yourself.

## What is OpenCVE

**OpenCVE** is a platform used to locally import the list of CVEs and perform searches on it (by vendors, products, CVSS, CWE...).

Users subscribe to vendors or products, and OpenCVE alerts them when a new CVE is created or when an update is done in an existing CVE.

## Features

- **Explore** the CVE database and filter the results by Vendor, Product, CVSS score or CWE

- **Subscribe** to vendors and products extracted from CPE

- **Be notified** for new CVE and for CVE updates based on subscriptions

- **Analyse** all CVE details (vendors, products, CVSS score, CPE, CWE, References...)

- **Create** custom tags (unread, important, devteam...) to organize the CVE list

- **Display** the history of each CVE and see their last changes in the homepage

- **Retrieve** the last changes in custom reports

- **Customize** the notification settings (frequency, filter by CVSS score...)

- **Integrate** OpenCVE with your own tools using the Rest API

You can use **for free** these features on the public instance: [https://www.opencve.io](https://www.opencve.io).

## How does it work

OpenCVE uses the [JSON feed](https://nvd.nist.gov/vuln/data-feeds#JSON_FEED) provided by the [NVD](https://nvd.nist.gov/) to update the local list of CVEs.

After an initial import, a background task is regularly executed to synchronize the local copy with the NVD feed. If a new CVE is added, or if a change is detected, the subscribers of the related vendors and products are alerted.



  



Read the [How It Works](https://docs.opencve.io/how-it-works/) guide to learn in details how OpenCVE works.

## Requirements

OpenCVE works with **Python >=3.7**.

It uses the JSONB feature for performance, so you will need a **PostgreSQL** instance to store the data (CVE, Users, Vendors, Products, Subscriptions, ...). Other engines are not supported.

The **pg_trgm** module of PostgreSQL is required to let you search in the CVEs list. The [upgrade-db](https://docs.opencve.io/commands/#upgrade-db) command will enable it for you, but you can also do it yourself if you prefer (`CREATE EXTENSION pg_trgm`). From PostgreSQL 13 this module is considered as trusted, meaning it can be installed by non-superusers with the CREATE privilege.

Celery is used to periodically fetch the NVD database and update the list of CVEs. For that you will need a broker : we recommend you **Redis** for the ease of installation. Futhermore it is possible that future versions of OpenCVE will use a cache feature, in that case the Redis requirement will already be filled for you.

During the import of initial data OpenCVE will download and parse huge files, like the CPE dictionnary. For that we recommend you **3.5G RAM** at least.

## Installation

We provide 2 methods to install OpenCVE :

- [manual installation](https://docs.opencve.io/installation/manual/)

- [docker installation](https://docs.opencve.io/installation/docker/)

The second method can be useful if you don't want to manage the dependencies (like PostgreSQL, Redis or Celery).

Check these documentations for the details of each step (initial import, admin creation, etc).
