Advisories

Skill ecosyste-ms/skills/skills/advisories

Query advisories.ecosyste.ms for security vulnerability metadata aggregated from GitHub Security Advisories, OSV, RustSec, ErlEf and others. Use when checking a package or repo for known CVEs, listing recent advisories for an ecosystem, or fetching CVSS/EPSS scores and patched version ranges.From its SKILL.md

ecosyste.ms Advisories API

Base URL: https://advisories.ecosyste.ms/api/v1

All responses are JSON. No auth required. Set a User-Agent header. Results are deduplicated by CVE across sources.

Full OpenAPI spec: https://advisories.ecosyste.ms/docs/api/v1/openapi.yaml

Look up advisories for a package or repo

By purl (include a version to get only advisories affecting that version) or by source repository URL:

curl -s 'https://advisories.ecosyste.ms/api/v1/advisories/lookup?purl=pkg:npm/[email protected]'
curl -s 'https://advisories.ecosyste.ms/api/v1/advisories/lookup?repository_url=https://github.com/rails/rails'

List and filter advisories

# all advisories for a package
curl -s 'https://advisories.ecosyste.ms/api/v1/advisories?ecosystem=pypi&package_name=django'

# critical severity only, newest first
curl -s 'https://advisories.ecosyste.ms/api/v1/advisories?ecosystem=npm&severity=CRITICAL&sort=published_at&order=desc'

# everything published since a date
curl -s 'https://advisories.ecosyste.ms/api/v1/advisories?created_after=2026-01-01T00:00:00Z'

Filters: ecosystem, package_name, severity (LOW/MODERATE/HIGH/CRITICAL), repository_url, source, created_after, updated_after, sort, order, page, per_page.

Single advisory

curl -s 'https://advisories.ecosyste.ms/api/v1/advisories/GHSA-jf85-cpcp-j695'

Sources

curl -s 'https://advisories.ecosyste.ms/api/v1/sources'

Response fields

uuid, title, description, severity, cvss_score, cvss_vector, epss_percentage, epss_percentile, published_at, withdrawn_at, identifiers (CVE/GHSA ids), references, repository_url, blast_radius, source_kind, packages[] (each with ecosystem, package_name, purl, versions[].vulnerable_version_range, versions[].first_patched_version, affected_versions, unaffected_versions).

When to use

Checking whether a specific package@version has known vulnerabilities
Auditing a project's dependency list against known CVEs
Finding the first patched version for an advisory
Tracking new advisories published for an ecosystem since a given date

Grouped from the skills themselves: near-identical wordings counted once, and counted by distinct author, so one author publishing three of these counts once. Length counted with cl100k_base; the agent that loads this file may tokenize it differently.
