No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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]
