The current version of Piwik is not affected by this vulnerability. Since version 0.5 (released December 2009), Piwik checks (and sets, if required) the MySQL connection charset to UTF-8.

Piwik users are, however, encouraged to upgrade to the latest versions of Piwik and PHP to take advantage of new features and bug fixes.
