MantisBT may expose private issues' summaries to unauthorized users
Impact
Due to insufficient access-level checks, any logged-in user allowed to perform Group Actions can get access to the _Summary_ field of private Issues (i.e. having Private view status, or belonging to a private Project) via a crafted bug_arr[] parameter in bug_actiongroup_ext.php.
