XSS is a variant on missing or lax input verification. Thus all other
forms of input-nonverification like buffer overflows or char(0)
injections or the like should be handeled similarily.

In its simplest version XSS could be used for phishing - which is bad
enough for banking or business portals. Depending on the application
other elevations might be possible through XSS like session stealing,
cmd/sql injects, etc.

Especially if such an elevated XSS was detected for a software it
definitely would have a place on security mailing lists. But it should
be more qualified than just "XSS found on ....". Just running a XSS
scanner is lame - whereas finding out all consequences and possible
attack vectors and maybe even posting a patch might be a worthwile
posting.
