WP security vuln query

http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-3544 shows WP 2.2.1 as still vulnerable to a security hole partially patched in the 2.2 -> 2.2.1 update. I can’t find references to this being resolved either in the CVE or in the wordpress.org site – can someone tell me if this was fixed? If so, in a release, or just in CVS?
