nvd-api 0.9.1

NVD API 2.0 Python API

NVD API client is a community driven NVD API 2.0 client. This client support Vulnerabilities API and Products API.

Getting Start

Products / CPE API

This API’s simple example is bellow.

from client import NvdApiClient
from pprint import pprint

client = NvdApiClient()

response = client.get_cpes(
    cpe_name_id="87316812-5F2C-4286-94FE-CC98B9EAEF53",
    results_per_page=1,
    start_index=0
)
pprint(response)

get_cpes method check API’s all constraints and limitations.

• cpeNameId and matchCriteriaId must be uuid format.

• cpeMatchString must be CPEv2.3 format.

• If filtering by keywordExactMatch, keywordSearch is REQUIRED.

• If filtering by the last modified date, both lastModStartDate and lastModEndDate are REQUIRED.

• resultsPerPage’s maximum allowable limit is 10,000.

• The maximum allowable range when using any date range parameters is 120 consecutive days.

Products / Match Criteria API

This API’s simple example is bellow.

from nvd_api import NvdApiClient
from pprint import pprint

client = NvdApiClient()

response = client.get_cpe_match(
    cve_id="CVE-2022-32223",
    results_per_page=1,
    start_index=0
)
pprint(response)

get_cpe_match method check API’s all constraints and limitations.

• cveId is must be CVE ID format.

• If filtering by the last modified date, both lastModStartDate and lastModEndDate are REQUIRED.

• matchCriteriaId must be uuid format.

• resultsPerPage’s maximum allowable limit is 5,000.

• The maximum allowable range when using any date range parameters is 120 consecutive days.

• cpeName must be CPEv2.3 format.

Vulnerabilities / CVE API

This API’s simple example is bellow.

from nvd_api import NvdApiClient
from pprint import pprint

client = NvdApiClient()

response = client.get_cves(
    cpe_name="cpe:2.3:o:debian:debian_linux:3.0:*:*:*:*:*:*:*",
    cvss_v2_metrics="AV:L/AC:L/Au:N/C:C/I:C/A:C",
    cvss_v2_severity="HIGH",
    results_per_page=1,
    start_index=1
)
pprint(response)

• cpeName must be CPEv2.3 format.

• cveId is must be CVE ID format.

• cvssV2Severity, cvssV2Metrics is must be CVSS v2 format.

• cvssV3Severity, cvssV3Metrics is must be CVSS v3 format.

• cweId is must be CWE ID format.

• resultsPerPage’s maximum allowable limit is 2,000.

• If filtering by keywordExactMatch, keywordSearch is REQUIRED.

• If filtering by the last modified date, both lastModStartDate and lastModEndDate are REQUIRED.

• If filtering by the last modified date, both pubStartDate and pubEndDate are REQUIRED.

• The maximum allowable range when using any date range parameters is 120 consecutive days.

• cvssV2Metrics cannot be used in requests that include cvssV3Metrics.

• cvssV3Metrics cannot be used in requests that include cvssV2Metrics.

• cvssV2Severity cannot be used in requests that include cvssV3Severity.

• cvssV3Severity cannot be used in requests that include cvssV2Severity.

Vulnerabilities / CVE Change History API

This API’s simple example is bellow.

from nvd_api import NvdApiClient
from pprint import pprint

client = NvdApiClient()

response = client.get_cve_history(
    change_start_date="2021-08-04T00:00:00.000",
    change_end_date="2021-10-23T00:00:00.000",
    event_name="CVE Rejected",
    results_per_page=1,
    start_index=1
)
pprint(response)

get_cve_history method check API’s all constraints and limitations.

• If filtering by the change date, both changeStartDate and changeEndDate are REQUIRED.

• cveId is must be CVE ID format.

• resultsPerPage’s maximum allowable limit is 5,000.

• The maximum allowable range when using any date range parameters is 120 consecutive days.

With API Key

If you have the nvd api key, you can set key to client.

from nvd_api import NvdApiClient
from pprint import pprint

client = NvdApiClient(wait_time=1 * 1000, api_key='THIS IS API KEY')

response = client.get_cves(
    cpe_name="cpe:2.3:o:debian:debian_linux:3.0:*:*:*:*:*:*:*",
    cvss_v2_metrics="AV:L/AC:L/Au:N/C:C/I:C/A:C",
    cvss_v2_severity="HIGH",
    results_per_page=1,
    start_index=1
)
pprint(response)

• api_key : api key published by nvd.

• wait_time : interval time to execute api (with api key is 50 requests in a rolling 30s window, without api key is 5 requests in a rolling 30s window)
