How this service works
Look up any CVE in the US National Vulnerability Database (NVD): CVSS 3.1 score and severity vector, weakness (CWE) classification, human summary and references. The authoritative answer when an agent needs to know how bad a vulnerability actually is. Use this when an agent needs to cVSS score, severity and references from NVD.
Output
Returns the CVE's CVSS 3.1 base score and severity vector string (e.g. AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), CWE weakness classification, a human-readable description of the vulnerability, and a list of authoritative references and advisories sourced directly from the NVD.
Example use cases
Triage incoming vulnerability alert
“We just got an alert about CVE-2023-44487 — can you pull its CVSS 3.1 score and severity vector from NVD so I can decide how urgently we need to patch?”
Security report enrichment
“I'm writing a security advisory and need the official NVD summary, CVSS score, CWE classification, and references for CVE-2022-22965 — can you grab all of that?”
Assess third-party library risk
“Our dependency scanner flagged CVE-2014-0160 in one of our libraries — how bad is it according to NVD? Give me the CVSS 3.1 score and a quick summary.”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/security/cve-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative CVSS 3.1 scoring, severity vectors, CWE classifications, and NVD-sourced summaries for a specific CVE identifier. Prefer it over general web search when you need structured, machine-readable vulnerability metadata that can be used programmatically in risk scoring, compliance reporting, or security triage workflows. Ideal when the agent needs a definitive, NVD-backed answer rather than community or vendor-specific assessments.
Side effects
- CVE ID not found in NVD — returns an error or empty result for CVEs not yet published or incorrectly formatted IDs
- Malformed CVE ID format (e.g. missing 'CVE-' prefix or invalid year/sequence) — may return validation error
- NVD upstream unavailability — may return timeout or service error
- Very recent CVEs may not yet have full CVSS scores assigned in NVD — partial data returned
- Rate limiting or payment failure may result in 402 or 429 responses
