Interchange lets unauthenticated users run code via quick question

CVE-2026-75031 · published 22 days ago

If the default settings are used, anyone on the internet could inject code and have it executed, potentially taking control of the system. Apply the recommended configuration changes or update to a patched version to stop this behavior.

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]
