Hi,
Today, I (more or less just by coincidence) found that an unknown user has access to my Jira instance. Since I am the admin of my sites, I am quite surprised how this happened.
The user is visible when managing viewer, it appears when searching for "pro";

However, this user not not visible in user admin in the "Administration" panel. When checking the Jira Apps, I see three plugins that have "Proforma" in name, so they could be connected to this user, but I am unaware why they are available.
Does anyone have an idea what this is? We don´t use "Proforma" and I would be happy to get rid of this (or at least disable it).
Regards,
Harald
