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 react/react published their own advisory on GitHub. Its facts and headline are shown here; the description stays on GitHub.
