National Vulnerability Database CPE/CVE API Library

Project description

Simple NIST NVD API wrapper library

License Written Documentation Status

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.


  • Search the NVD for CVEs using all parameters allowed by the NVD 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 ( to allow for 0.6 seconds between requests. Otherwise it is 6 seconds between requests.


$ pip install nvdlib


>>> import nvdlib
>>> r = nvdlib.getCVE('CVE-2021-26855')
>>> print(r.v3severity + ' - ' + str(r.v3score))
   CRITICAL - 9.8
>>> print(r.cve.description.description_data[0].value)
   Microsoft Exchange Server Remote Code Execution Vulnerability This CVE ID is unique from CVE-2021-26412, 
   CVE-2021-26854, CVE-2021-26857, CVE-2021-26858, CVE-2021-27065, CVE-2021-27078.
>>> print(r.v3vector)


Run the tests with

$ pip install -e '.[dev]'
$ pytest


More information

This is my first attempt at creating a library while utilizing all my Python experience from classes to functions.
