check_cve

Use this when the user asks how serious a CVE is, such as "how bad is CVE-2021-44228?". Pass the CVE id. Returns a priority (exploited, likely, routine or unknown), the description, CVSS score and severity, whether the CISA Known Exploited Vulnerabilities catalog lists it, the EPSS exploitation probability, a patch or advisory link when tagged, and the as_of dates. A lookup by CVE id: it does not know which software the user runs or whether they are affected.

Parameters1

cve

string

required

A CVE id such as "CVE-2021-44228"

Raw schema

{
  "type": "object",
  "properties": {
    "cve": {
      "type": "string",
      "pattern": "^[Cc][Vv][Ee]-[0-9]{4}-[0-9]{4,19}$",
      "maxLength": 30,
      "description": "A CVE id such as \"CVE-2021-44228\""
    }
  },
  "required": [
    "cve"
  ],
  "additionalProperties": false
}

check_cves

Rank several CVEs. Use this when the user has a list of CVE ids and wants to know which to deal with first, such as "which of these CVEs should I patch first?". Pass up to 10 CVE ids. Returns each one's priority, CVSS score, CISA exploited-list status and EPSS score, most urgent first, with a count per priority. An id NVD could not be asked about in this call is marked deferred; ask for it again later. It does not know which software the user runs.

Parameters1

cves

array

required

Up to 10 CVE ids

    }
  },
  "required": [
    "cves"
  ],
  "additionalProperties": false
}

list_recent_kev

Use this when the user asks what CISA recently added to its Known Exploited Vulnerabilities list, such as "what exploited CVEs were added this month?". Optionally pass how many days back (up to 90), a product word to filter by, and a limit. Returns each CVE with its CISA name, the date it was added, CISA's due date and its CVSS score, newest first. The catalog lists vulnerabilities with evidence of exploitation; it is not a list of every serious CVE.

Parameters3

days	integer	optional	How many days back to look (default 30)
keyword	string	optional	Only entries whose name contains this word, such as "Chrome" or "Cisco"
limit	integer	optional	How many entries to return, newest first (default 20)

      "description": "How many entries to return, newest first (default 20)"
    }
  },
  "additionalProperties": false
}

triage_dependencies

Use this when the user wants to know which vulnerable dependencies to fix first, such as "which dependencies in this package-lock.json should I upgrade first?" or "triage my requirements.txt". Pass the text of a package-lock.json, package.json or requirements.txt as manifest, or a packages list of ecosystem, name and exact version (npm, pypi, go, crates.io, maven, rubygems, nuget, packagist); only names and versions are read. Returns fix_first: by default the 3 packages to upgrade first, each with a priority (malicious, exploited, likely, routine or unknown), one line on why, the CVE ids and the version that fixes it, then a short list of the other vulnerable packages and a count per priority. It matches exact package versions to known advisories; it does not scan code or show that the vulnerable code is reached.

Parameters3

packages	array	optional	Installed packages: ecosystem (npm, pypi, go, crates.io, maven, rubygems, nuget, packagist), name and exact version. Up to 300.
manifest	string	optional	The text of a package-lock.json (best: exact versions), a package.json (ranges read at their lowest version) or a requirements.txt (only == pins). Only names and versions are read.
limit	integer	optional	How many packages to put in fix_first (default 3)

Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Parameters3

kind	string	required	need_tool: a tool you want. need_data: data a tool lacks. bug: something broke. other: anything else about the tools.
