CVE-2009-4459

Redmine 0.8.7 and earlier uses the title tag before defining the character encoding in a meta tag, which allows remote attackers to conduct cross-site scripting (XSS) attacks and inject arbitrary script via UTF-7 encoded values in the title parameter to a new issue page, which may be interpreted as script by Internet Explorer 7 and 8.
