Advisory

Source description from Wordfence Intelligence.

Direct static code injection vulnerability in WordPress 2.0.2 and earlier allows remote attackers to execute arbitrary commands by inserting a carriage return and PHP code when updating a profile, which is appended after a special comment sequence into files in (1) wp-content/cache/userlogins/ (2) wp-content/cache/users/ which are later included by cache.php, as demonstrated using the displayname argument.
