What is the license of the wolfi and chainguard secdb?

[pombredanne]

I could not find any license information for the secdb data for wolfi and chainguard.
Can you clarify what would be the license?
These are the data published at:

• https://packages.wolfi.dev/os/security.json
• https://packages.cgr.dev/chainguard/security.json

I need a license to integrate this in https://github.com/nexb/vulnerablecode

For reference, the Alpine secdb has a license at https://secdb.alpinelinux.org/license.txt
Something similar would be awesome!
Thanks

PS: I am not sure if this issue should be filed only here, or at https://github.com/chainguard-dev/vulnerability-scanner-support/ or should be split in two? Please advise!
