           Summary: XSS vulnerability in the OPAC search results interface
 Change sponsored?: ---
           Product: Koha
           Version: HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P5
         Component: OPAC

In opac-search.pl:

foreach my $sort (@sort_by) {
    $template->param($sort => 1);   # FIXME: security hole.  can set any
TMPL_VAR here
}

This makes it pretty easy for someone to do things like inject arbitrary HTML
and Javascript, and so steal the credentials of another user.

This operation needs a whitelist of valid values that it checks against.
