November 15, 2024:  NVD Technical Update
CVE List Authorized Data Publisher (ADP) Support
We plan to deploy changes to our systems the week of November 18th. After this is complete, NVD systems will begin ingesting supported datatypes within the CVE List from all sources (CNAs and ADPs). 

What does this mean?
CVE records within the NVD dataset will contain more information (Reference(s), CWE, and CVSS) from additional sources. This new information will be displayed on the website and in the API responses, attributed to the organization who contributed the information. More information regarding ADPs can be reviewed at https://www.cve.org/ProgramOrganization/ADPs.

Downstream data consumers will notice a large shift in the volume of CVE Record modifications as part of this change. Going forward, organizations should expect CVE records to update at a higher frequency.

Other relevant changes:
Duplicate References and Reference Tags

As part of NVD enrichment efforts, reference tags are associated with each reference provided by a specific source. In instances where the same reference is provided by multiple sources, any reference tags associated to an existing reference will be applied to the newly provided, duplicate reference automatically.

Changes to NVD CVE Record Change History

• Event Names are now more consistently ordered when they are recorded at the same timestamp.
• Event Content (Actions and Change Types) will now be more consistently ordered.
• Reference and Reference Tag (Type) changes will now be audited separately across all cases.
• “CVE Received” Events will be re-labeled as “New CVE Received.” Using the “CVE Received” eventName parameter for the /cvehistory/ API will still return the appropriate results.

CVE API and Vulnerability Search Impacts
Due to upstream removal of data points used by the NVD systems, the following parameters will no longer filter search results. 

• CVE API: HasCertAlerts, HasCertNotes, HasOval
• Vulnerability Search:  US-CERT Technical Alerts, US-CERT Vulnerability Notes, OVAL Queries

These options will be removed in a future release.

November 13, 2024:  NVD General Update
This update provides information on our progress as we work to process all incoming Common Vulnerabilities and Exposures (CVEs) and to address the backlog of CVEs that built up earlier this calendar year.

We now have a full team of analysts on board, and we are addressing all incoming CVEs as they are uploaded into our system. In addition, we have addressed all Known Exploited Vulnerabilities (KEVs) that were in the backlog, and we are processing all new KEVs as they come in.

However, our initial estimate of when we would clear the backlog was optimistic. This is due to the fact that the data on backlogged CVEs that we are receiving from Authorized Data Providers (ADPs) are in a format that we are not currently able to efficiently import and enhance.

To address this issue, we are developing new systems that will allow us to process incoming ADP data more efficiently. We are working to complete this project as quickly as possible and will continue to provide updates on our progress to this NVD Updates page.

May 29, 2024: NIST has awarded a contract for additional processing support for incoming Common Vulnerabilities and Exposures (CVEs) for inclusion in the National Vulnerability Database. We are confident that this additional support will allow us to return to the processing rates we maintained prior to February 2024 within the next few months.

In addition, a backlog of unprocessed CVEs has developed since February. NIST is working with the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) to facilitate the addition of these unprocessed CVEs to the NVD. We anticipate that that this backlog will be cleared by the end of the fiscal year. 

As we shared earlier, NIST is also working on ways to address the increasing volume of vulnerabilities through technology and process updates. Our goal is to build a program that is sustainable for the long term and to support the automation of vulnerability management, security measurement and compliance.

With a 25-year history of providing this database of vulnerabilities to users around the world and given that we do not play an enforcement or oversight role, NIST is uniquely suited to manage the NVD. NIST is fully committed to maintaining and modernizing this important national resource that is vital to building and maintaining trust in information technology and fostering innovation. 

Moving forward, we will keep the community informed of our progress toward normal operational levels and our future modernization plans.

April 25, 2024: NIST maintains the National Vulnerability Database (NVD), a repository of information on software and hardware flaws that can compromise computer security. This is a key piece of the nation’s cybersecurity infrastructure.

There is a growing backlog of vulnerabilities submitted to the NVD and requiring analysis. This is based on a variety of factors, including an increase in software and, therefore, vulnerabilities, as well as a change in interagency support. Currently, we are prioritizing analysis of the most significant vulnerabilities. In addition, we are working with our agency partners to bring on more support for analyzing vulnerabilities and have reassigned additional NIST staff to this task as well.

We are also looking into longer-term solutions to this challenge, including the establishment of a consortium of industry, government, and other stakeholder organizations that can collaborate on research to improve the NVD.

NIST is committed to its continued support and management of the NVD. Currently, we are focused on our immediate plans to address the CVE backlog, but plan to keep the community posted on potential plans for the consortium as they develop. For questions and concerns, you can contact nvd [at] nist.gov (nvd[at]nist[dot]gov).

April 9, 2024: To enable more flexibility within our API output we need to remove certain restrictions from the existing 2.0 API schemas. All existing API users will need to download the latest schema files to avoid validation issues later this year. See /cves/ schema restriction update.

March 5, 2024: As part of ongoing efforts to increase the reliability and general responsiveness of the 2.0 APIs, the NVD will be making a change to the Match Criteria API. See /cpematch/ resultsPerPage update.

May 20, 2024: On May 8, 2024, the Common Vulnerabilities and Exposures (CVE) program deployed support for the CVE 5.1 record format. Once the deployment started, NIST was not able to process records with the new format until we released a subsequent deployment for NVD-related systems on May 14, 2024. We are now ingesting both CVE 5.0 and CVE 5.1 records into the NVD dataset on an hourly basis and we’re working as fast as we can to return to normal processing.
