If the security level is set to 'Could be a security issue', then you need to be logged in to view the issue. If the security level is set higher than this, you need to be in a certain group to be able to view it.
After a security issue is fixed, sometimes the level is changed to allow more people to view it. Otherwise, the security announcement will provide enough information so that it is not necessary to view the tracker issue.
