Get EPSS (Exploit Prediction Scoring System) score for one or more CVEs. Returns the probability of exploitation within 30 days and percentile ranking.

Get the top CVEs ranked by EPSS exploitation probability. Shows the most likely-to-be-exploited vulnerabilities.

Check if CVE(s) are in CISA's Known Exploited Vulnerabilities (KEV) catalog. KEV entries are actively exploited in the wild and require urgent patching.

Search CISA KEV catalog by vendor, product, or keyword. Find known exploited vulnerabilities for specific technologies.

Get recently added entries to CISA KEV catalog. Monitor for newly confirmed actively-exploited vulnerabilities.

Search GitHub Advisory Database for security advisories. Filter by ecosystem (npm, pip, maven, etc.), severity, or CVE/GHSA ID.

Get full details of a GitHub security advisory by GHSA ID or CVE ID. Includes affected packages, CVSS, and patch information.

Query Google OSV for known vulnerabilities affecting a specific package version. Supports all major ecosystems (npm, PyPI, Maven, Go, etc.).

Get full vulnerability details from OSV by ID. Accepts OSV IDs (OSV-xxx), GHSA IDs (GHSA-xxx), CVE IDs (CVE-xxx), or ecosystem-specific IDs (PYSEC-xxx, RUSTSEC-xxx).

Batch query OSV for vulnerabilities across multiple packages at once. Efficient for scanning a dependency list.

Search for public PoC exploits and exploit code for a CVE on GitHub. Returns repositories with proof-of-concept code, sorted by stars.

Look up a CWE (Common Weakness Enumeration) by ID or search by keyword. Returns name, description, and category for the top 40+ most common CWEs.

Get full CWE details from the MITRE CWE REST API. Returns name, description, related weaknesses, applicable platforms, consequences, detection methods, and mitigations for any of the 1000+ CWEs.

Get CWE parent/child hierarchy. Shows which weaknesses are more general (parents) and more specific (children) variants of a given CWE.

Get the MITRE CWE Top 25 Most Dangerous Software Weaknesses for a given year. Shows the most impactful vulnerability classes ranked by frequency and severity.

Parse a CVSS v3.x or v4.0 vector string into a human-readable breakdown. Explains each metric, calculates the base score, and provides a plain-English summary. Supports both CVSS:3.1 and CVSS:4.0 format.

Look up a CVE via Shodan CVEDB (zero-auth). Returns CVSS score, EPSS probability, KEV status, affected CPEs, and references — all in one call without any API key.

Find CVEs affecting a specific product or vendor via Shodan CVEDB. No API key required. Returns CVEs with CVSS, EPSS, and KEV status.

Get known vulnerabilities for an IP address via Shodan InternetDB. Returns open ports, hostnames, CPEs, CVE IDs, and tags. No API key required.

Check VulnCheck's extended KEV catalog for a CVE. Contains ~80% more entries than CISA KEV, including exploit maturity and ransomware association data.

Search for vulnerabilities by CPE (Common Platform Enumeration) string via VulnCheck. Useful for finding all CVEs affecting a specific software version.

Search for vulnerabilities by Package URL (purl) via VulnCheck. Supports all major ecosystems (npm, PyPI, Maven, Go, etc.).

Look up a CVE in Vulners database. Returns detailed vulnerability information including exploit references, CVSS scores, and related advisories from 200+ sources.

Full-text vulnerability search across 200+ sources via Vulners. Search for exploits, advisories, patches, and vulnerability reports by keyword.

Check if a Nuclei detection template exists for a CVE. Nuclei templates from ProjectDiscovery enable automated vulnerability scanning. Returns template URL, severity, and tags.

Check if a Metasploit exploit module exists for a CVE. If a module exists, the vulnerability is weaponized and should be prioritized for patching.

Search the NVD CPE (Common Platform Enumeration) dictionary by keyword. Find standardized product identifiers for use in vulnerability queries.

Get CPE match criteria for a specific CVE from NVD. Shows exactly which product versions are affected, including version ranges.

Get CVE details from CIRCL (Computer Incident Response Center Luxembourg). Returns CAPEC attack patterns, vulnerable products, and access/impact vectors. No API key required.

Get community assessments for a CVE from AttackerKB. Shows attacker value, exploitability ratings, and Rapid7 analysis from security researchers.

Map CWE weakness IDs to MITRE ATT&CK techniques. Shows which attack techniques a vulnerability enables, useful for threat modeling and detection engineering.

Full CVE enrichment — queries NVD, EPSS, KEV, GitHub Advisory, OSV, Shodan CVEDB, VulnCheck, Nuclei Templates, and Metasploit in parallel for comprehensive vulnerability intelligence. Returns CVSS, exploitation probability, KEV status, affected packages, exploit availability, and a computed risk score.

Rank a list of CVEs by exploitation risk. Combines CVSS score, EPSS probability, KEV status, and weaponization signals (Nuclei/Metasploit modules) into a unified risk score. Higher score = patch first.
