index.php in WordPress 2.0.3 allows remote attackers to obtain sensitive information, such as SQL table prefixes, via an invalid paged parameter, which displays the information in an SQL error message.

Cross-site scripting (XSS) vulnerability in wp-db-backup.php in WordPress 2.0.11 and earlier, and possibly 2.1.x through 2.3.x, allows remote attackers to inject arbitrary web script or HTML via the backup parameter in a wp-db-backup.php action to wp-admin/edit.php.

SQL injection vulnerability in template-functions-category.php in WordPress 1.5.1 allows remote attackers to execute arbitrary SQL commands via the $cat_ID variable, as demonstrated using the cat parameter to index.php.

Cross-site scripting (XSS) vulnerability in the paging links functionality in template-functions-links.php in Wordpress 1.5.2, and possibly other versions before 2.0.1, allows remote attackers to inject arbitrary web script or HTML to Internet Explorer users via the request URI ($_SERVER['REQUEST_URI']).

SQL injection vulnerability in WordPress 1.5.2, and possibly other versions before 2.0, allows remote attackers to execute arbitrary SQL commands via the User-Agent field in an HTTP header for a comment.

Multiple "unannounced" cross-site scripting (XSS) vulnerabilities in WordPress before 2.0.2 allow remote attackers to inject arbitrary web script or HTML via unknown attack vectors.

Multiple cross-site scripting (XSS) vulnerabilities in post.php in WordPress 1.5.1.2 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) p or (2) comment parameter.

Cross-site scripting (XSS) vulnerability in the wp_explain_nonce function in the nonce AYS functionality (wp-includes/functions.php) for WordPress 2.0 before 2.0.9 and 2.1 before 2.1.1 allows remote attackers to inject arbitrary web script or HTML via the file parameter to wp-admin/templates.php, and possibly other vectors involving the action variable.
