EchelonGraph CVE & Exposure

Vendor advisory detail

get_vendor_advisory

Read-onlyIdempotent

One vendor advisory in full, by vendor and the vendor's advisory ID (the vendor and vendor_advisory_id of a vendor advisory row, never its advisory_id, EchelonGraph's internal UUID): title, description, severity, cvss_v3_score, cve_ids and known_cve_ids (those with a record in EchelonGraph's CVE feed), affected_products, remediation, references, vendor_modified_at, and withdrawn_at and withdrawn_reason when the vendor withdrew it. remediations lists each remediation the vendor lists, with kind (the vendor's own category, never read from the text: vendor_fix, workaround, mitigation, no_fix_planned, none_available or other), source_category, text, url and the cve_ids and product_ids it covers; each text is the vendor's, verbatim, untested by EchelonGraph. remediation_state is parsed, none_in_source, not_parsed or withdrawn: none_in_source and not_parsed are not a finding that no fix exists. Each advisory carries vendor_published_at (the vendor's date), our_first_seen_at (when EchelonGraph first recorded it) and withdrawn (true: the vendor rescinded it). Each advisory also carries rejected_cve_ids: the CVE IDs it names whose CVE record was rejected (withdrawn) by its numbering authority, which are not active vulnerabilities. coverage.vendor_window is that vendor's window in what EchelonGraph holds: vendor, advisories, earliest_vendor_published_at, latest_vendor_published_at, held_since (where that window begins) and history_backfill (in_progress or not_started: older advisories not all held yet); null when the windows could not be read or carry none for that vendor. measured_at is our_first_seen_at. Its freshness is null: the answer carries no poll-completion time. Past 30,000 characters of JSON, the first text block holds data cut to fit, and the note says what the cut leaves out and where to read it (TEXT CUT); so is structured data (DATA CUT), unless full: true.

Input Schema

Name	Required	Description
`full`	No	true: data in the structured result is the answer whole, however long. Without it, a structured result past 30,000 characters of JSON has its data cut (DATA CUT): in an order the note states, the entries of its longest lists keep only some of their fields, and then the lists only some of their entries; data_truncated is true, and truncated gives each list cut with its total, the number returned and whether its entries are thinned. Whole data is for a program; a client that sizes structured results, as Claude Code does against MAX_MCP_OUTPUT_TOKENS, can refuse an answer past its cap.
`vendor`	Yes	the vendor slug, e.g. microsoft, redhat, github
`advisory_id`	Yes	the vendor's own advisory ID, a row's vendor_advisory_id, e.g. RHSA-2024:1234, GHSA-xxxx-xxxx-xxxx or CVE-2024-3400; not a row's advisory_id, EchelonGraph's internal UUID
