CWEs

Which weakness types show up in our CVE corpus, and which controls address them?

This index covers all 760 CWEs cited by at least one CVE across the NVD records we ingest — split into frequent (434, cited ≥10 times) and rare (326, 1–9 times). Frequent weaknesses link to a detail page with the NIST 800-53 r5 controls that address them (LLM-proposed) and their top CVEs ranked by Risk Priority; rarer ones link out to MITRE. Below the search, the blind spot — 194 live weaknesses no CVE has ever been tagged with.

The blind spot: 194 weaknesses no CVE reports

These are live (non-deprecated) weakness types in the MITRE catalogue that no CVE in our corpus has ever been tagged with. Many are design-level weaknesses NVD analysts rarely reach for — the kind of systemic flaw that never gets its own advisory. Each links to MITRE's canonical definition.

Catalogue summary

Mapped weaknesses by abstraction level. Coverage is heavily concentrated: 63.3% of all 340,103 CVE→CWE tags land on just the top 20 CWEs. A further 14,318 tags point at 41 retired category ids MITRE prohibits for mapping (e.g. CWE-264, CWE-399) — those CVEs carry no usable weakness mapping and are excluded here.
