Comment # 6 on bug 1118736 from George Anchev

Something more: It seems impossible to change personal data which is displayed
in bugzilla. I have just edited my personal info through the microfocus.com
account and the changes are not reflected here. Practically there is no way to
control personal data.

Raising the severity to major. This is definitely against GDPR because the
personal data is not in control of the user.
