WordPress is a popular personal publishing platform with a web
When decoding trackbacks with alternate character sets, WordPress does
not correctly sanitize the entries before further modifying a SQL
query. WordPress also displays different error messages in wp-login.php
based upon whether or not a user exists. David Kierznowski has

An attacker could also determine if a WordPress user existed by trying
to login as that user, better facilitating brute force attacks. Lastly,

browsers viewing /wp-admin/templates.php.

All WordPress users should upgrade to the latest version:
