Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: remove wide gentoo CPE. This does not appear to be Gentoo-specific such that Gentoo should be set as a platform CPE and it is nonsense to have every version of a distro flagging as vulnerable.
