In the interchange/interchange project, a critical remote code execution (RCE) vulnerability was found in the
“quick question” admin feature. In default installations arbitrary Perl
code can be injected and executed server-side by unauthenticated users.
The Perl code normally runs within a Safe container which limits the
scope of what it can do, unless the non-default AllowGlobal directive is
configured for the catalog being accessed.CTOR]
