cKEV Index Launches to Prioritize Vulnerabilities as AI Accelerates Exploit Development

CyberOK has introduced the open cKEV Index, a catalog of high-priority vulnerabilities ranked by the Urgent Patch Score (UPS) methodology. The index incorporates timelines of events such as exploit publication, proof-of-concept releases, and confirmed attacks to help organizations prioritize patching under resource constraints. It addresses the growing gap between rapid AI-assisted vulnerability discovery and slower remediation processes at both vendors and customers. Examples from Anthropic reports highlight how threat actors used AI agents for reconnaissance, code analysis, and exploit development against Android apps and web applications. Microsoft and Oracle have publicly linked increased vulnerability findings and larger patch releases to AI tooling. The UPS framework defines progressive phases from Radar to Emergency/IR, allowing teams to act on strong signals without waiting for full confirmation. An open version of the catalog is now available with detailed event histories for Urgent Patch and Emergency stages.

cKEV Index Launches to Prioritize Vulnerabilities Using Urgent Patch Score Methodology

CyberOK has introduced the open cKEV Index, a catalog of high-priority vulnerabilities based on the Urgent Patch Score (UPS) framework that tracks signals such as exploit publication and confirmed attacks. The index addresses the growing gap between accelerated vulnerability discovery powered by AI and the slower pace of patching, testing, and deployment in real environments. It incorporates timelines from sources including Anthropic reports on AI-assisted campaigns GTG-50014 and GTG-50029, the rust-in-peace framework, Microsoft Exchange Server Subscription Edition delays, and Oracle’s record 1,434 CVE fixes. UPS defines progressive phases from Radar to Emergency/IR, allowing teams to link specific events like PoC releases or CISA KEV additions to concrete actions under resource constraints. Research using 2025 CISA KEV data shows that early signals enable 35–53% of patches to be completed before official exploitation confirmation. The public version displays only Urgent Patch and Emergency stages with event histories, while full data and API access are available to CyberOK customers.
