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.
The maintainers of WordPress/wordpress-develop published their own advisory on GitHub. Reviewed sources take precedence over it.
