Five failure classes in CVE triage emerge: chained vulnerabilities that look harmless in isolation, rapid patch weaponization by nation-state actors, long-term stockpiled exploits that stay unpatched, identity gaps outside CVSS scoring, and AI-accelerated vulnerability discovery that overwhelms existing triage pipelines.

A forward-looking analysis shows CVSS misses real-world risk in these five failure modes, as demonstrated by exposure patterns in the Palo Alto Networks vulnerabilities CVE-2024-0012 and CVE-2024-9474 during Operation Lunar Peek.

Real-world impact is measured in minute-to-day exploitation timelines, underscoring the need for governance that treats identity gaps and AI-driven credentials as vulnerabilities and for patch-management and triage to adapt to an increasingly accelerated threat landscape.

CVSS base scores are insufficient for prioritization because they evaluate single vulnerabilities without context; enhancements like EPSS and CISA's SSVC are needed to reflect exploitation probability and decision logic.

The security director’s action plan maps the five failures to concrete steps: audit chain dependencies on KEV CVEs, slash KEV-to-patch SLAs for internet-facing systems, create a KEV aging report for board visibility, embed identity-surface controls into vulnerability reporting, and stress-test triage pipelines against exponential volume growth.

Concrete illustrations accompany each failure: authentication bypass (CVE-2024-0012) and privilege escalation (CVE-2024-9474) demonstrate compound risks; CrowdStrike data shows rapid exploitation; references to Salt Typhoon and chained exploits; a social-engineering help-desk example; and AI-driven discovery like Anthropic’s Claude Mythos uncovering vulnerabilities at scale.
