with the url below, privilege escalation is possible
The exploit can be simulated triggering
/cgi-bin/koha/members/member-flags.pl?member=42&newflags=1&flag=superlibrarian
Test plan:
Trigger the url above
=> Without this patch, 42 is now superlibrarian
=> With this patch, you will get the "Wrong CSRF token" error.
