Sadly this is not a problem on our side. This is a (known) problem by the BSI. They are working on a fix.
You can double check here and see, that their official feed doesn’t contain any newer advisories currently.
When there are new advisories, they will also get into our feed!
Thank you for the information - we thought the same in the first place. But they told us that they have issues with their system. Even if they have these new information feed - what about all the old advisories? In the past these got updated frequently, but do not receive any updates, anymore.
The new advisories have a new ID format and are published since the second of June.
What ever it is, I will roll up this topic internally again!
