JIRA please but remember to set the two security properties. Security Level (internal) And Security Severity as appropriate. You may not be able to see it once you have raised it.
If you can't see those properties then please email me and I'll forward your concern to the right people.
JIRA offers only the Field Security Severity but not Security Level.
When you say email - since I haven't got your E-Mail-Address - do you mean a private message in this forum using the function available in your userprofile?
