WordPress allows remote attackers to obtain sensitive information via a direct request for wp-admin/admin-functions.php, which reveals the path in an error message.

Cross-site request forgery (CSRF) vulnerability in the AdminPanel in WordPress 2.1.1 and earlier allows remote attackers to perform privileged actions as administrators, as demonstrated using the delete action in wp-admin/post.php. NOTE: this issue can be leveraged to perform cross-site scripting (XSS) attacks and steal cookies via the post 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.

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.

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.

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 wp-admin/templates.php in WordPress 2.0.5 allows remote attackers to inject arbitrary web script or HTML via the file parameter. NOTE: some sources have reported this as a vulnerability in the get_file_description function in wp-admin/admin-functions.php.

WordPress before 2.0.5 does not properly store a profile containing a string representation of a serialized object, which allows remote authenticated users to cause a denial of service (application crash) via a string that represents a (1) malformed or (2) large serialized object, because the object triggers automatic unserialization for display.

WordPress 2.0.2 through 2.0.5 allows remote attackers to obtain sensitive information via a direct request for (1) 404.php, (2) akismet.php, (3) archive.php, (4) archives.php, (5) attachment.php, (6) blogger.php, (7) comments.php, (8) comments-popup.php, (9) dotclear.php, (10) footer.php, (11) functions.php, (12) header.php, (13) hello.php, (14) wp-content/themes/default/index.php, (15) links.php, (16) livejournal.php, (17) mt.php, (18) page.php, (19) rss.php, (20) searchform.php, (21) search.php, (22) sidebar.php, (23) single.php, (24) textpattern.php, (25) upgrade-functions.php, (26) upgrade-schema.php, or (27) wp-db-backup.php, which reveal the path in various error messages. NOTE: another researcher has disputed the details of this report, stating that version 2.0.5 does not exist. NOTE: the admin-footer.php, admin-functions.php, default-filters.php, edit-form-advanced.php, edit-link-form.php, edit-page-form.php, kses.php, locale.php, rss-functions.php, template-loader.php, and wp-db.php vectors are already covered by CVE-2006-0986. The edit-form-comment.php, vars.php, and wp-settings.php vectors are already covered by CVE-2005-4463. The menu-header.php vector is already covered by CVE-2005-2110.
