Find vulnerabilities affecting a product by searching the NIST National Vulnerability Database. Pass product (free-text keyword, e.g. "apache log4j", "openssl", "wordpress plugin contact-form-7") or cpe (an exact CPE 2.3 name, e.g. cpe:2.3:a:apache:log4j:2.14.1:*:*:*:*:*:*:*). Returns matching CVEs newest-first, each with its id, description, CVSS base score/severity/vector, and dates. Optional limit (1–50). For "what CVEs affect X" / surveying a product's vulnerability history — distinct from security.cve, which resolves a single CVE id across NVD + CISA KEV + EPSS. Free, keyless.
