Fencer Intel 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: Fix incorrect CPE that was pointing to jenkins openid plugin rather than oic-auth. Also adds the fixed in version.
