How this service works
CVE lookup
Output
Returns a JSON object containing: the canonical advisory ID, a boolean ok status, a one-line summary of the vulnerability, an array of CVSS severity vectors and ratings from upstream advisories, and an EPSS object from FIRST.org with a probability score (0–1), percentile (0–1), and the date of the score.
Example use cases
Triage incoming security alert
“We just got an alert about CVE-2022-22965 — can you pull up its CVSS severity and EPSS score so I can decide how urgently we need to patch?”
Assess open source dependency flaw
“I found GHSA-35jh-r3h4-6jhm referenced in our package audit — what does it actually do, how bad is it, and how likely is it to be exploited in the wild?”
Security report enrichment
“I'm writing a vulnerability report and need the official summary, CVSS rating, and EPSS percentile for CVE-2023-44487 — can you grab those details for me?”
Technical details
Endpoint
GEThttps://vulnfeed-api.novadyne.ai/vulnscan/cve/CVE-2021-44228When to prefer
Choose this endpoint when you need structured, machine-readable vulnerability details — especially EPSS exploit probability scores — for a specific CVE or GHSA identifier. It is well-suited for security automation pipelines, triage bots, and dependency audit workflows where you need both severity (CVSS) and real-world exploit likelihood (EPSS) in a single call. Prefer it over generic web search when you need structured JSON output rather than prose, and over full dependency scanners when you already have the specific advisory ID.
Side effects
- Unknown or malformed CVE/GHSA ID returns empty or error response
- Very recently disclosed CVEs may not yet be indexed
- EPSS data may be absent for very new or obscure advisories
- Payment failure (x402) prevents the request from completing
- Rate limiting may occur under high query volume
