GCVE: A Decentralized Model for Vulnerability Identification, Publication, and Operational Enrichment

Computer Science > Cryptography and Security [Submitted on 30 May 2026] GCVE: A Decentralized Model for Vulnerability Identification, Publication, and Operational Enrichment Alexandre Dulaunoy The Global CVE initiative (GCVE) proposes a decentralized, open, and extensible model for vulnerability identification, publication, and enrichment. It addresses a gap in today's vulnerability ecosystem: centralized systems provide rigorous control and widely recognized identifiers, while many producers publish advisories independently without a shared fabric for discovery, correlation, enrichment, and reuse. This paper presents GCVE as a socio-technical standardization effort combining autonomous GCVE Numbering Authorities, lightweight allocation rules, distributed publication, open Best Current Practices, and practical reference implementations. The model preserves global uniqueness while allowing participants to publish according to their operational needs. It also broadens the concept of a vulnerability record to cover assignments, disclosures, sightings, rejected identifiers, observations, exploited vulnerability information, and enrichment records. The paper describes how the GCVE BCP process supports technical interoperability and amendable operational practice, including practical guidance for vulnerability handling and disclosure. It also examines the extension mechanism, including AI-oriented extensions, as a way to evolve the standard without centralizing control. A particular focus is placed on vulnerability-lookup as the reference implementation. It aggregates multiple sources, supports GCVE publication and consumption, implements distributed Known Exploited Vulnerability data, and enables automatically enriched vulnerability data streams. Building on lessons from the MISP ecosystem, GCVE frames vulnerability coordination not only as identifier allocation, but as open infrastructure for collective security knowledge production.
