Q: I know that X-Ray gathers vulnerabilities information from external sources, but one of the artifacts I have has an issue and I would like this information to exist in my company. How can I do this?
A: You can create an issue(s) of your own for your localized artifacts (e.g. org/maven/mylibrary) which are most likely unique. Therefore, external information will not be available on such artifacts.
For example, your QA team could create an internal issue which enhances the data available on artifacts that have been indexed. Do so by going to [X-Ray UI] → [Components] → [Actions] → [Assign Custom Issue]
