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: Prometheus is a go application and the web ui component is vulnerable; however, most applications using the prometheus go library as a go dependency will not be using the UI components and therefore w.
