https://www.eclipse.org/security/known/index.xml is empty

The https://www.eclipse.org/security/known/ shows several recent CVEs. It also indicates that the info should be available as an RSS feed at https://www.eclipse.org/security/known/index.xml:

<link rel="alternate" href="/security/known/index.xml" type="application/rss+xml" title="">

But that address returns an empty feed:
