parlay will take a CycloneDX (JSON, XML) or SPDX 2.3 (JSON) document and enrich it with information taken from external services. At present this includes:
By enrich, we mean add additional information. You put in an SBOM, and you get a richer SBOM back. In many cases SBOMs have a minimum of information, often just the name and version of a given package. By enriching that with additional information we can make better decisions about the packages we're using.
Let's take a simple CycloneDX SBOM of a Javascript application. Using parlay we enrich it using data from ecosyste.ms, adding information about the package license, external links, the maintainer and more.
$ cat testing/sbom.cyclonedx.json
...
{
"bom-ref": "[email protected]",
"type": "library",
"name": "subtext",
"version": "6.0.12",
"purl": "pkg:npm/[email protected]"
}
...
$ cat testing/sbom.cyclonedx.json | parlay ecosystems enrich - | jq
...

What about with SPDX? Let's take an SBOM containing a list of packages like so:
{
"name": "concat-map",
"SPDXID": "SPDXRef-7-concat-map-0.0.1",
"versionInfo": "0.0.1",
"downloadLocation": "NOASSERTION",
"copyrightText": "NOASSERTION",
"externalRefs": [
{
"referenceCategory": "PACKAGE-MANAGER",
"referenceType": "purl",
"referenceLocator": "pkg:npm/[email protected]"
}
]
}Running parlay ecosystems enrich <sbom.spdx.json> will add additional information:
{
"name": "concat-map",
"SPDXID": "SPDXRef-7-concat-map-0.0.1",
"versionInfo": "0.0.1",
"downloadLocation": "NOASSERTION",
+ "homepage": "https://github.com/ljharb/concat-map",
+ "licenseConcluded": "MIT",
"copyrightText": "NOASSERTION",
+ "description": "concatenative mapdashery",
"externalRefs": [
{
"referenceCategory": "PACKAGE-MANAGER",
"referenceType": "purl",
"referenceLocator": "pkg:npm/[email protected]"
}
]There are a few other utility commands for ecosyste.ms as well. The first returns raw JSON information about a specific package from ecosyste.ms:
parlay ecosystems package pkg:npm/snyk
You can also return raw JSON information about a specific repository:
parlay ecosystems repo https://github.com/open-policy-agent/conftest
parlay can also enrich an SBOM with Vulnerability information from Snyk.
It's important to note vulnerability data is moment-in-time information. By adding vulnerability information directly to the SBOM this makes the SBOM moment-in-time too.
Note the Snyk commands require you to be a Snyk customer, and require passing a valid Snyk API token in the SNYK_TOKEN environment variable.
The API base url can be set using the SNYK_API environment variable, and if missing it will default to https://api.snyk.io/rest.
parlay snyk enrich testing/sbom.cyclonedx.json
Snyk will add a new vulnerability attribute to the SBOM, for example:
"vulnerabilities": [
{
"bom-ref": "[email protected]",
"id": "SNYK-JS-SUBTEXT-467257",
"ratings": [
{
"source": {
"name": "Snyk",
"url": "https://security.snyk.io"
},
"score": 7.5,
"severity": "high",
"method": "CVSSv31",
"vector": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"

}For SPDX, vulnerability informatio is added as additional externalRefs:
{
"referenceCategory": "SECURITY",
"referenceType": "advisory",
"referenceLocator": "https://security.snyk.io/vuln/SNYK-JS-MINIMATCH-3050818",

"referenceType": "advisory",
"referenceLocator": "https://security.snyk.io/vuln/SNYK-JS-MINIMATCH-1019388",
"comment": "Regular Expression Denial of Service (ReDoS)"
}Return raw JSON information about vulnerabilities in a specific package from Snyk:
parlay snyk package pkg:npm/[email protected]
The OpenSSF Scorecard project tests various aspects of a projects security posture and provides a score. parlay supports added a link to this data with the parlay scorecard enrich command.
You can use this like so:
parlay scorecard enrich testing/sbom2.cyclonedx.json
This will currently add an external reference to the Scorecard API which can be used to retrieve the full scorecard.
{
"bom-ref": "103-org.springframework:[email protected]",
"type": "library",
"name": "org.springframework:spring-webmvc",
"version": "5.3.3",
"purl": "pkg:maven/org.springframework/[email protected]",
"externalReferences": [
{
"url": "https://api.securityscorecards.dev/projects/github.com/spring-projects/spring-framework",
"comment": "OpenSSF Scorecard",
"type": "other"
}
]
},We're currently looking at the best way of encoding some of the scorecard data in the SBOM itself as well.
There are lots of other sources of package data, and it would be great to add support for them in parlay. Please open issues and PRs with ideas.
parlay is a fan of stdin and stdout. You can pipe SBOMs from other tools into parlay, and pipe between the separate enrich commands too.
Maybe you want to enrich an SBOM with both ecosyste.ms and Snyk data:
cat testing/sbom.cyclonedx.json | ./parlay e enrich - | ./parlay s enrich - | jq
Maybe you want to take the output from Syft and add vulnerabilitity data?
syft -o cyclonedx-json nginx | parlay s enrich - | jq
Maybe you want to geneate an SBOM with cdxgen, enrich that with extra information, and test that with bomber:
cdxgen -o | parlay e enrich - | bomber scan --provider snyk -
The ecosyste.ms enrichment adds license information, which Bomber then surfaces:
■ Ecosystems detected: gem
■ Scanning 18 packages for vulnerabilities...
■ Vulnerability Provider: Snyk (https://security.snyk.io)
■ Files Scanned

■ Licenses Found: MIT, Apache-2.0, BSD-3-Clause, Ruby
parlay binaries are available from GitHub Releases. Just select the archive for your operating system and architecture. For instance, you could download for macOS ARM machines with the following, substituting {version} for the latest version number, for instance 0.1.4.
wget https://github.com/snyk/parlay/releases/download/v{version}/parlay_Darwin_arm64.tar.gz
tar -xvf parlay_Darwin_arm64.tar.gz
The various services used to enrich the SBOM data have data for a subset of purl types:
apkcargococoapodscomposergemgolanghexmavennpmnugetpypi
apkcargococoapodscomposerdebgemgolanghexmavennpmnugetpypirpmswift
apkcargococoapodscomposergemgolanghexmavennpmnugetpypi
Note that Scorecard data is available only for a subset of projects from supported Git repositories. See the Scorecard project for more information.
