The weekly Vulnerability Summary — the Monday roundup of everything the National Vulnerability Database ingested that week — goes away after the September 28 edition. CISA frames the cut as fallout from June's move away from ranking bugs by raw CVSS score, though it hasn't really explained why the bulletin gets killed rather than reworked to fit the new model. The likelier reason is volume: AI-assisted research is filing CVEs faster than a weekly email can reasonably carry, and NVD's backlog hasn't made the math easier. If that summary was part of your triage, rewire now — the KEV catalog, the cybersecurity advisories feed, and the CVE list are where the signal moves to.
