How this service works
Details of a CVE by id: description, CVSS score, severity and vector, CWE, whether it is in CISA's Known Exploited list, affected products (CPE) and references, from NVD with CVE.org fallback. Use for security triage and patch prioritisation.
Output
A structured record for the requested CVE including: description of the vulnerability, CVSS base score and severity level (e.g. Critical/High/Medium/Low), CVSS vector string, associated CWE identifier(s), a flag indicating whether the CVE appears in CISA's Known Exploited Vulnerabilities (KEV) catalog, a list of affected products in CPE format, and external references such as advisories and patches. Data is sourced from NVD with a fallback to CVE.org.
Example use cases
Log4Shell patch prioritization triage
“Give me the CVE details for CVE-2021-44228 including its CVSS score, severity, CVSS vector, and whether it's in the CISA Known Exploited Vulnerabilities catalog so I can decide how urgently we need to patch.”
XZ Utils backdoor affected product check
“Look up CVE-2024-3094 for me — I need to know which products and CPEs are affected, the CWE, and the full description so I can assess our exposure.”
HTTP/2 Rapid Reset severity assessment
“What's the CVSS score and severity for CVE-2023-44487? Also tell me if it's actively exploited and include any references so our security team can review the advisories.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/dev/cve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need comprehensive, authoritative vulnerability metadata for a specific CVE ID — including CVSS scoring, CISA KEV status, CWE classification, and affected CPE data — for security triage, patch prioritization, or risk assessment workflows. Prefer this over general web search when you need structured, machine-readable vulnerability data with NVD provenance.
Side effects
- Invalid or malformed CVE ID returns an error or empty result
- CVE ID not yet published in NVD or CVE.org returns no data
- Very recently disclosed CVEs may not yet have CVSS scores assigned
- Network timeout or upstream NVD/CVE.org unavailability causes failure
- Missing cve_id parameter results in a 400-level validation error
