I’ve recently discovered that the EU has their own vulnerability database: EUVD.

As noted by the message on top of the page:

This website is currently in its beta phase. We appreciate your collaboration in reporting any inaccurate or incomplete information via the link below “Provide feedback”.

The site is still in a really early stage, but hopefully it gains a bit more traction as the future of other vulnerability databases is uncertain (for instance, with CVE almost dying abruptly due to a contract ending).

As of now, there also are no feeds (RSS more particularly) to watch this database, so hopefully this will be added soon.
