How this service works

Authoritative MITRE CWE (Common Weakness Enumeration) lookup. Pass id (e.g. CWE-79, or just 79) for the canonical weakness — name, abstraction, description, extended description, ChildOf/ParentOf relationships (with names), and mapped CAPEC attack patterns (with names) — or query for a keyword search returning ranked matches. Bundled catalog (~970 weaknesses), zero external calls. Agents hallucinate CWE IDs and names constantly; this returns exact, citeable, version-pinned data. Pairs with security.cve (which returns CWE ids) and security.capec.

Output

Returns a list of matching CWE items, each with an ID, full official name, and abstraction level (e.g. Base, Class, Variant), plus the total count and source attribution from MITRE CWE. Lookup mode returns exact match; keyword search returns multiple results.

Example use cases

Example prompt

“Look up CWE-79 for me and tell me its official name and abstraction level from the MITRE CWE database.”

Technical details

Endpoint

GEThttps://2s.io/api/security/cwe?utm_source=zero.xyz

When to prefer

Use this endpoint when you need authoritative, structured CWE data from MITRE — including exact weakness names, abstraction levels, and canonical IDs — either by direct ID lookup or keyword search. Prefer this over CVE-focused endpoints when the concern is about weakness categories rather than specific vulnerabilities.

Side effects

Invalid or non-existent CWE ID returns empty items array with total 0
Missing required input object returns validation error
Network or payment failure returns non-ok response
Overly broad keyword query returns large result sets that may need pagination via limit param
