Simple NIST NVD API wrapper library

NVDlib is a Python library that allows you to interface with the NIST National Vulnerability Database (NVD), pull vulnerabilities (CVEs), and Common Platform Enumeration (CPEs) into easily accessible objects.

Features

  • Search the NVD for CVEs using all parameters allowed by the NVD API (recently updated to utilize version 2 of the API). Including search criteria such as CVE publish and modification date, keywords, severity, score, or CPE name.
  • Search CPE names by keywords, CPE match strings, or modification dates. Then pull the CVE ID's that are relevant to those CPEs.
  • Retrieve details on individual CVEs, their relevant CPE names, and more.
  • Built in rate limiting according to NIST NVD recommendations.
    Get an API key (https://nvd.nist.gov/developers/request-an-api-key) to allow for a delay argument to be passed. Otherwise it is 6 seconds between requests by default.

Install

$ pip install nvdlib
