Interchange Quick Question Admin Remote Code Execution Bug

A critical remote code execution (RCE) vulnerability has been found in the Interchange project's "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 that limits what it can do, unless the non-default AllowGlobal directive is configured for the catalog being accessed.
