CISA decides weekly vulnerability bulletin isn't necessary anymore
The Cybersecurity and Infrastructure Security Agency (CISA) has announced the discontinuation of its weekly vulnerability bulletin effective September 28, 2026. This decision aligns with a shift toward a modern, risk-based approach that prioritizes real-world exploitation risks over static CVSS scores. Security professionals are advised to rely on CISA's known exploited vulnerabilities catalog and cybersecurity advisories for critical updates.
- ▪CISA will stop publishing its weekly vulnerability bulletin on September 28, 2026.
- ▪The agency is moving away from static CVSS scores to prioritize vulnerabilities based on real-world risk factors like exploitability and control granted.
- ▪AI-assisted security research has increased the volume of vulnerabilities, making the previous weekly format less effective.
- ▪Users are instructed to subscribe to CISA's known exploited vulnerabilities catalog and cybersecurity advisories to receive critical notices.
- ▪The change is part of a June Binding Operational Directive aimed at improving mission readiness for federal civilian agencies.
