I agree that it would be good to have a solution that would allow
list-admins to put HTML tags or even just "&" characters in some of
these fields. Currently, the 'info' field is treated specially and
allows anything but a </?script.*> tag. Everything else is fully HTML
The purpose of this is to prevent XSS attacks presumably by list
admins. Since the contents of these fields are displayed on the admin
web pages regardless of how they are entered, if list admins are
deemed untrustworthy at the site level, they shouldn't be allowed to
put this stuff in by any method.
I personally know very little about XSS attacks and am unable to
comment intelligently on how much security is required.
