How this service works
Patch priority P0-P3 for a CVE from CISA exploited-in-the-wild status, EPSS exploit probability and advisory severity.
Output
A structured JSON object containing: a P0–P3 patch priority verdict, the list of reasons behind the verdict, a human-readable summary, EPSS exploit probability and percentile, CISA KEV record (if present) including vendor, product, date added, due date, ransomware use, and required action, advisory severity, source attribution, and flags for degraded data or unchecked signals.
Example use cases
Triage critical Log4Shell vulnerability
“Give me the patch priority for CVE-2021-44228 — I need to know if it's in CISA's KEV list, what the EPSS probability is, and whether we're talking P0 or P1 urgency.”
Automate vulnerability triage in CI/CD pipeline
“My scanner just flagged CVE-2023-44487 in our infrastructure — what's the patch priority verdict, and is there a CISA remediation deadline I need to know about?”
Ransomware risk assessment for a CVE
“Is CVE-2022-30190 associated with ransomware use, what priority should it get, and what's the CISA required action for it?”
Technical details
Endpoint
GEThttps://vuln-intel.x402tookit.com/vuln-cve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, actionable patch priority decision (P0–P3) for a specific CVE, combining CISA KEV exploitation evidence, EPSS probability, and advisory severity into one verdict — rather than looking up each signal separately. Ideal for vulnerability triage workflows, security automation pipelines, or when a human needs a clear 'how urgent is this?' answer backed by authoritative data sources.
Side effects
- Invalid or malformed CVE ID returns an error or null verdict
- CVE not found in any data source returns a low-confidence or degraded result
- Upstream EPSS or CISA KEV data temporarily unavailable triggers degraded mode with partial results
- Rate limiting or payment failure returns HTTP 402
- Very new CVEs may not yet have EPSS scores or advisory data, resulting in incomplete signals
