The title is not a problem, since clicking it only returns you to this thread, not the site
The link that was in the post, has now been deactivated.
Bots repeating or caching this post will still keep that "link", not active but as text, so if the site is "problematic", we shouldn't be spreading it (neither as link nor as text).
So it is still recommended to edit the title. Generally speaking, the title of the posts / topics shouldn't contain "URLs" or similar, no matter if they have some security issue or not. It is like free publicity, and this shouldn't be tolerated here.
I have also edited the title of this particular post (as all the participants of this topic should).
