The Coverage Lie: Why Current Vulnerability Scanners Fail to Stop Breaches

Version scanning lies by omission: only ~6% of CVEs are exploited. Nuclei validates exploitability at runtime with matchers, extractors, and multi-step flows, as the 2025 CrushFTP cases illustrate.

Nuclei Templates v10.4.2 and v10.4.3 ship 226 new templates covering 123 CVEs—about 10 actively exploited KEV entries—and push deeper into AI/LLM attack surface with 27 first-time contributors joining.

Community-driven Nuclei templates stay enterprise-grade: each YAML template is lab-reproduced, checklist-hardened, and double-reviewed, proving exploitability instead of guessing from versions.

Nuclei Templates v10.2.1/v10.2.2 add 106 templates covering 57 CVEs, including 10 KEVs like Ivanti EPMM RCE and Versa Concerto auth bypass. A template bounty program and real-time update bot launched.

Most breaches don't begin with a zero-day but with something ordinary like a forgotten server, an unmanaged network device, a service reachable across a segment that was supposed to be isolated. Internal scanning was supposed to catch exactly that but most scanners match a host's banner and version against a CVE list and flag everything potentially affected, so the few reachable exposures sit lost among thousands that were never exploitable. That noise is expensive now that the window to respon
