CSAF v2.0 is ready for testing and implementation

OASIS is pleased to announce that Common Security Advisory Framework Version 2.0 from the OASIS Common Security Advisory Framework (CSAF) TC [1] has been approved as an OASIS Committee Specification.

The Common Security Advisory Framework (CSAF) is a language to exchange Security Advisories formulated in JSON. CSAF v2.0 is the definitive reference for the language which supports creation, update, and interoperable exchange of security advisories as structured information on products, vulnerabilities and the status of impact and remediation among interested parties.

This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.
