CVE / NVD Explorer

Look up any CVE and search vulnerabilities from Claude, ChatGPT, or any MCP assistant, with no setup. This curated KBrain answers from authoritative sources: the National Vulnerability Database (NVD) for the description, CVSS score and vector, weakness (CWE), and affected products; the CISA Known Exploited Vulnerabilities (KEV) catalog for confirmed active exploitation; FIRST.org EPSS for the probability that a vulnerability will be exploited soon; and the EU Vulnerability Database (ENISA EUVD) for the European cross-reference and its EUVD id. Every record is refreshed daily and carries a last-updated timestamp, so answers stay current instead of relying on a model's training data. Ask for a single CVE, look it up by its EUVD id, search by product or vendor, list what shipped this week, check KEV status, or triage a list by real risk. No self-hosting and no API keys to manage.
