The CVE Program approved updated CVE Numbering Authority (CNA) Rules that broaden how vulnerabilities can be assigned identifiers and clarify which CNA should handle a report. The revised framework introduces a right-of-first-refusal model that favors the CNA with the most appropriate scope, adopts more technology-neutral criteria for deciding whether an issue merits a CVE, and adds clearer guidance on what types of findings do and do not qualify for assignment.
The changes are expected to affect vulnerability management by increasing flexibility for CNAs and potentially expanding coverage to issues that previously sat in gray areas, including some cloud misconfigurations and certain supply-chain compromises. The updated guidance still leaves open questions around shared code, protocols, specifications, and upstream dependencies, with examples such as HTTP/2 CONTINUATION Flood and HTTP/2 Rapid Reset illustrating the continuing ambiguity over how broadly CVEs should be assigned.
