CVSS scored these two Palo Alto CVEs as manageable. Chained, they gave attackers root access to 13,000 devices.

During Operation Lunar Peek in November 2024, attackers gained unauthenticated remote admin access — and eventual root — across more than 13,000 exposed Palo Alto Networks management interfaces. Palo Alto Networks scored CVE-2024-0012 at 9.3 and CVE-2024-9474 at 6.9 under CVSS v4.0. NVD scored the same pair 9.8 and 7.2 under CVSS v3.1. Two scoring systems. Two different answers for the same vulnerabilities. The 6.9 fell below patch thresholds. Admin access appeared required. The 9.3 sat queued for maintenance. Segmentation would hold.

"Adversaries circumvent [severity ratings] by chaining vulnerabilities together," Adam Meyers, SVP of Counter Adversary Operations at CrowdStrike, told VentureBeat in an exclusive interview on April 22, 2026. On the triage logic that missed the chain: "They just had amnesia from 30 seconds before."

Both CVEs sit on the CISA Known Exploited Vulnerabilities catalog. Neither score flagged the kill chain. The triage logic that consumed those scores treated each CVE as an isolated event, and so did the SLA dashboards and the board reports those dashboards feed.

CVSS did exactly what it was designed to do. Score one vulnerability at a time. The problem is that adversaries do not attack one vulnerability at a time.

"CVSS base scores are theoretical measures of severity that ignore real-world context," wrote Peter Chronis, former CISO of Paramount and a security leader with Fortune 100 experience. By moving beyond CVSS-first prioritization at Paramount, Chronis reported reducing actionable critical and high-risk vulnerabilities by 90%. Chris Gibson, executive director of FIRST, the organization that maintains CVSS, has been equally direct: using CVSS base scores alone for prioritization is "the least apt and accurate" method, Gibson told The Register. FIRST's own EPSS and CISA's SSVC decision model address part of this gap by adding exploitation probability and decision-tree logic.

Five triage failure classes CVSS was never designed to catch

In 2025, 48,185 CVEs were disclosed, a 20.6% year-over-year increase. Jerry Gamblin, principal engineer at Cisco Threat Detection and Response, projects 70,135 for 2026. The infrastructure behind the scores is buckling under that weight. NIST announced on April 15 that CVE submissions have grown 263% since 2020, and the NVD will now prioritize enrichment for KEV and federal critical software only.

1. Chained CVEs that look safe until they aren't

The Palo Alto pair from Operation Lunar Peek is the textbook. CVE-2024-0012 bypassed authentication. CVE-2024-9474 escalated privileges. Scored separately under both CVSS v4.0 and v3.1, the escalation flaw filtered below most enterprise patch thresholds because admin access appeared required. The authentication bypass upstream eliminated that prerequisite entirely. Neither score communicated the compound effect.

Meyers described the operational psychology: teams assessed each CVE independently, deprioritized the lower score, and queued the higher one for maintenance.

2. Nation-state adversaries who weaponize patches within days

The CrowdStrike 2026 Global Threat Report documented a 42% year-over-year increase in vulnerabilities exploited as zero-days before public disclosure. Average breakout time across observed intrusions: 29 minutes. Fastest observed breakout: 27 seconds. China-nexus adversaries weaponized newly patched vulnerabilities within two to six days of disclosure.

"Before it was Patch Tuesday once a month. Now it's patch every day, all the time. That's what this new world looks like," said Daniel Bernard, Chief Business Officer at CrowdStrike. A KEV addition treated as a routine queue item on Tuesday becomes an active exploitation window by Thursday.

3. Stockpiled CVEs that nation-state actors hold for years

Salt Typhoon accessed senior U.S. political figures' communications during the presidential transition by chaining CVE-2023-20198 with CVE-2023-20273 on internet-facing Cisco devices, a privilege escalation pair patched in October 2023 and still unapplied more than a year later. Compromised credentials provided a parallel entry vector. The patches existed. Neither was applied.

Sixty-seven percent of vulnerabilities exploited by China-nexus adversaries in 2025 were remote code execution flaws providing immediate system access, according to the CrowdStrike 2026 Global Threat Report. CVSS does not degrade priority based on how long a CVE has gone unpatched. No board metric tracks aging KEV exposure.

That silence is the vulnerability.

4. Identity gaps that never enter the scoring system

A 2023 help desk social engineering call against a major enterprise produced more than $100 million in losses. No CVE was assigned. No CVSS score existed. No patch pipeline entry was created. The vulnerability was a human process gap in identity verification, sitting entirely outside the scoring system's aperture.

"A pro needs a zero day if all you have to do is call the help desk and say I forgot my password," Meyers said.

Agentic AI systems now carry their own identity credentials, API tokens, and permission scopes, operating outside traditional vulnerability management governance. Merritt Baer, CSO at Enkrypt AI, has argued on record that identity-surface controls are vulnerability equivalents belonging in the same reporting pipeline as software CVEs. In most organizations, help desk authentication gaps and agentic AI credential inventories live in a separate governance silo. In practice, nobody's governance.

5. AI-accelerated discovery that breaks pipeline capacity

Anthropic's Claude Mythos Preview demonstrated autonomous vulnerability discovery, finding a 27-year-old signed integer overflow in OpenBSD's TCP SACK implementation across roughly 1,000 scaffold runs at a total compute cost under $20,000. Meyers offered a thought-experiment projection in the exclusive interview with VentureBeat: if frontier AI drives a 10x volume increase, the result is approximately 480,000 CVEs annually. Pipelines built for 48,000 break at 70,000 and collapse at 480,000. NVD enrichment is already gone for non-KEV submissions.

"If the adversary is now able to find vulnerabilities faster than the defenders or the business, that's a huge problem, because those vulnerabilities become exploits," said Daniel Bernard, Chief Business Officer at CrowdStrike.

CrowdStrike on Thursday launched Project QuiltWorks, a remediation coalition with Accenture, EY, IBM Cybersecurity Services, Kroll, and OpenAI formed to address the vulnerability volume that frontier AI models are now generating in production code. When five major firms build a coalition around a pipeline problem, no single organization's patch workflow can keep pace.

Security director action plan

The five failure classes above map to five specific actions.

Run a chain-dependency audit on every KEV CVE in the environment this month. Flag any co-resident CVE scored 5.0 or above, the threshold where privilege escalation and lateral movement capabilities typically appear in CVSS vectors. Any pair chaining authentication bypass to privilege escalation gets triaged as critical regardless of individual scores.

Compress KEV-to-patch SLAs to 72 hours for internet-facing systems. The CrowdStrike 2026 Global Threat Report breakout data, 29-minute average and 27-second fastest, makes weekly patch windows indefensible in a board presentation.

Build a monthly KEV aging report for the board. Every unpatched KEV CVE, days since disclosure, days since patch availability, and owner. Salt Typhoon exploited a Cisco CVE patched 14 months earlier because no escalation path existed for aging exposure.

Add identity-surface controls to the vulnerability reporting pipeline. Help desk authentication gaps and agentic AI credential inventories belong in the same SLA framework as software CVEs. If they sit in a separate governance silo, they sit in nobody's governance.

Stress-test pipeline capacity at 1.5x and 10x current CVE volume. Gamblin projects 70,135 for 2026. Meyers's thought-experiment projection: frontier AI could push annual volume past 480,000. Present the capacity gap to the CFO before the next budget cycle, not after the breach that proves the gap existed.
