VULNARCHIVE and GNA 1988: Automated Vulnerability Identifier Allocation in a Federated GCVE Ecosystem.
One of the core ideas behind GCVE is that vulnerability identification does not need to depend on a single central authority. Independent GCVE Numbering Authorities (GNAs) can operate their own processes, allocation policies and publication infrastructure while remaining interoperable with the wider GCVE ecosystem.
VULNARCHIVE is a new example of this model in practice. It has been assigned GNA 1988 and can automatically allocate identifiers.
Automatic allocation does not mean blind allocation. The system separates evidence collection, matching, review and publication, allowing uncertain cases to be reviewed while well-defined cases can flow through the pipeline automatically.

WTF: An anonymous security researcher has published working exploit code for a total of 15 previously unknown vulnerabilities without first notifying the affected manufacturers and open-source projects: #OpenSource #Vulnerability

Tired of drafting vulnerability advisories from Git patches?
We developed patch2vuln to facilitate the creation of security advisories directly from Git patches.
With a single command, patch2vuln can assist an analyst throughout the advisory creation process: analyzing the patch, drafting the vulnerability title and description, identifying CWE and CAPEC mappings, proposing a CVSS v4.0 vector, extracting affected versions, remediation information and credits, and generating a structured CVE/GCVE record.
The analysis can run entirely locally using an LLM via Ollama, while deterministic processing is used for elements such as CVSS scoring and structured output validation.
The goal is not to replace the security analyst, but to remove much of the repetitive work and provide a solid structured draft for human review and publication.
patch2vuln v1.0 is now available as open-source software under the @… Lab initiative.

Pretty cool idea from @… - a bot to analyse fucked up references from the CVE records.
@…
Maybe we could imagine an archive bot at the same time to ensure that the references don't get lost. Just like archive.org or similar. Maybe something for @… to look into.

From a research paper to running open-source code in just a few days.
We (with @…) have been experimenting in Vulnerability-Lookup with the concept of Local Exploit Hazard, based on the recent research paper “Modeling Local Exploit Hazard — A Bayesian Framework for Quantifying Exploit Risk and Operational Efficiency” by Stephen Shaffer and Laura Cristiana Voicu.
The idea addresses an important question in vulnerability management:
Not simply “How dangerous is this vulnerability globally?” but “How much exploitation risk does this vulnerability represent in my environment?”
Instead of introducing yet another static vulnerability score, the model starts from exploit likelihood such as EPSS and combines it with local security controls, CVSS attack vectors, vulnerability age and KEV policy to estimate an exploitation hazard.
We implemented an experimental version in Vulnerability-Lookup and connected it directly to operational workflows.

vulnerability-lookup 6.0 will be released this week with many (really, many!) new features.
One of the smaller, but important, additions is support for multiple SSVC views alongside CVSS. When SSVC information is available from an ADP (such as CISA) , or from additional sources such as GCVE, it is now displayed by default.
This allows users to more easily compare the different severity and prioritization assessments associated with a vulnerability.
The CIRCL vulnerability-lookup instance is running the pre-release of 6.0 -

I love to see clever use of the @… ecosystem and @… did a cool GNA which is automatically creating GCVE records and structured security advisories from full-disclosure mailing-list or alike:

GCVE BCP-07, the Known Exploited Vulnerability (KEV) Assertion Format, has been updated to version 2.2. A key addition is the formalisation of the GCVE KEV Directory, a simple machine-readable directory allowing organisations to announce where their KEV catalogues and exploitation assertions are published.
We particularly encourage software and hardware vendors to publish their own KEV catalogues. Vendors are often in the best position to confirm exploitation affecting their products, and publishing this information in a machine-readable form can significantly improve vulnerability prioritisation for users, CSIRTs and vulnerability-management platforms.

If you are curious about (nearly) everything we did the past months at the GCVE.eu initiative:

Sightings have long been a major topic of discussion in the CTI community, particularly in the field of vulnerability management. We have now published a GCVE BCP to standardise the format that has been implemented, tested and used operationally in Vulnerability-Lookup for some time.
Thanks to everyone (Cédric Bonhomme, Éireann Leverett, Andras Iklody, Sami Mokaddem and many more) who participated in discussions and worked on the implementation details of sightings over the past several years. These efforts had a strong focus on practical implementation, while BCP-12 specifically addresses sightings in the context of vulnerability management.
BCP-12 is still a draft open for review, but it already provides a strong foundation for existing implementations.

The @… BCP-07 KEV format has been updated to allow the Withdrawn and Reasserted KEV Assertions.
This allows to support case like CVE-2026-69836 .
