CISA review makes the case for eliminating vulnerability classes

CISA's FY2024-2025 vulnerability review urges eliminating recurring vulnerability classes, finding 41.5% of 2025 KEV entries map to persistent 'stubborn weaknesses'.

CISA's Vulnerability Review for fiscal years 2024 and 2025 found most compromises stemmed from opportunistic exploitation of known, exposed vulnerabilities rather than nation-state zero-days or advanced tradecraft. The review found 41.5% of 2025 KEV catalog entries map to 'stubborn weaknesses' - injection flaws, improper input validation, memory-safety failures, path traversal and broken access control - recurring on the CWE Top 25 since 2019. CISA advocates Secure by Design practices, vulnerability class elimination, and buyer-driven 'Secure by Demand' contract requirements, while warning that AI-enabled vulnerability discovery will soon accelerate exploitation.
