vars.php in WordPress 2.0.2, possibly when running on Mac OS X, allows remote attackers to spoof their IP address via a PC_REMOTE_ADDR HTTP header, which vars.php uses to redefine $_SERVER['REMOTE_ADDR'].

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']).

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.

Cross-site scripting (XSS) vulnerability in WordPress 2.0.0 allows remote attackers to inject arbitrary web script or HTML via scriptable attributes such as (1) onfocus and (2) onblur in the "author's website" field. NOTE: followup comments to the researcher's web log suggest that this issue is only exploitable by the same user who injects the XSS, so this might not be a vulnerability

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.
