Cross-site scripting (XSS) vulnerability in wp-includes/general-template.php in WordPress before 20070309 allows remote attackers to inject arbitrary web script or HTML via the year parameter in the wp_title function.

SQL injection vulnerability in xmlrpc (xmlrpc.php) in WordPress 2.1.2, and probably earlier, allows remote authenticated users to execute arbitrary SQL commands via a string parameter value in an XML RPC mt.setPostCategories method call, related to the post_id variable.

Cross-site scripting (XSS) vulnerability in wp-admin/vars.php in WordPress before 2.0.10 RC2, and before 2.1.3 RC2 in the 2.1 series, allows remote authenticated users with theme privileges to inject arbitrary web script or HTML via the PATH_INFO in the administration interface, related to loose regular expression processing of PHP_SELF.

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.

wp-admin/user-edit.php in WordPress before 2.0.5 allows remote authenticated users to read the metadata of an arbitrary user via a modified user_id parameter.

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.

Multiple directory traversal vulnerabilities in plugins/wp-db-backup.php in WordPress before 2.0.5 allow remote authenticated users to read or overwrite arbitrary files via directory traversal sequences in the (1) backup and (2) fragment parameters in a GET request.

Multiple unspecified vulnerabilities in WordPress before 2.0.4 have unknown impact and remote attack vectors. NOTE: due to lack of details, it is not clear how these issues are different from CVE-2006-3389 and CVE-2006-3390, although it is likely that 2.0.4 addresses an unspecified issue related to "Anyone can register" functionality (user registration for guests).

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.

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 the "post comment" functionality of WordPress 2.0.1 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) name, (2) website, and (3) comment parameters.

WordPress 2.0.1 and earlier allows remote attackers to obtain sensitive information via a direct request to (1) default-filters.php, (2) template-loader.php, (3) rss-functions.php, (4) locale.php, (5) wp-db.php, and (6) kses.php in the wp-includes/ directory; and (7) edit-form-advanced.php, (8) admin-functions.php, (9) edit-link-form.php, (10) edit-page-form.php, (11) admin-footer.php, and (12) menu.php in the wp-admin directory; and possibly (13) list directory contents of the wp-includes directory. NOTE: the vars.php, edit-form.php, wp-settings.php, and edit-form-comment.php vectors are already covered by CVE-2005-4463. The menu-header.php vector is already covered by CVE-2005-2110. Other vectors might be covered by CVE-2005-1688. NOTE: if the typical installation of WordPress does not list any site-specific files to wp-includes, then vector [13] is not an exposure.

WordPress before 1.5.2 allows remote attackers to obtain sensitive information via a direct request to (1) wp-includes/vars.php, (2) wp-content/plugins/hello.php, (3) wp-admin/upgrade-functions.php, (4) wp-admin/edit-form.php, (5) wp-settings.php, and (6) wp-admin/edit-form-comment.php, which leaks the path in an error message related to undefined functions or failed includes. NOTE: the wp-admin/menu-header.php vector is already covered by CVE-2005-2110. NOTE: the vars.php, edit-form.php, wp-settings.php, and edit-form-comment.php vectors were also reported to affect WordPress 2.0.1.
