Sources

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.

The maintainers of venueless/venueless published their own advisory on GitHub. Reviewed sources take precedence over it.
