Today, CISA published When to Issue Vulnerability Exploitability eXchange (VEX) Information, developed by a community of industry and government experts with the goal to offer some guidance and structure for the software security world, including the large and growing global SBOM community.
This guide explains the circumstances and events that could lead an entity to issue VEX information and describes the entities that create or consume VEX information. Whether, and when, to issue VEX information is a business decision for most suppliers and possibly a more individual decision for independent open source developers. This document identifies factors that influence the decision.
