WordPress — свободно распространяемая система управления содержимым сайта с открытым исходным кодом.

wp-trackback.php in WordPress 2.0.6 and earlier does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary SQL commands via the tb_id parameter. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in WordPress.

WordPress before 2.0.6, when mbstring is enabled for PHP, decodes alternate character sets after escaping the SQL query, which allows remote attackers to bypass SQL injection protection schemes and execute arbitrary SQL commands via multibyte charsets, as demonstrated using UTF-7.

wp-login.php in WordPress 2.0.5 and earlier displays different error messages if a user exists or not, which allows remote attackers to obtain sensitive information and facilitates brute force attacks.

Cross-site scripting (XSS) vulnerability in the CSRF protection scheme in WordPress before 2.0.6 allows remote attackers to inject arbitrary web script or HTML via a CSRF attack with an invalid token and quote characters or HTML tags in URL variable names, which are not properly handled when WordPress generates a new link to verify the request.
