WordPress 2.2.x and 2.3.x allows remote attackers to obtain sensitive information via an invalid p parameter in an rss2 action to the default URI, which reveals the full path and the SQL database structure.

Multiple cross-site scripting (XSS) vulnerabilities in WordPress 2.0.9 and earlier allow remote attackers to inject arbitrary web script or HTML via the popuptitle parameter to (1) wp-admin/post.php or (2) wp-admin/page-new.php.

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 wp-includes/query.php in WordPress 2.3.1 and earlier allows remote attackers to execute arbitrary SQL commands via the s parameter, when DB_CHARSET is set to (1) Big5, (2) GBK, or possibly other character set encodings that support a "\" in a multibyte character.

Wordpress 1.5 through 2.3.1 uses cookie values based on the MD5 hash of a password MD5 hash, which allows attackers to bypass authentication by obtaining the MD5 hash from the user database, then generating the authentication cookie from that hash.

Multiple PHP remote file inclusion vulnerabilities in the BackUpWordPress 0.4.2b and earlier plugin for WordPress allow remote attackers to execute arbitrary PHP code via a URL in the bkpwp_plugin_path parameter to (1) plugins/BackUp/Archive.php; and (2) Predicate.php, (3) Writer.php, (4) Reader.php, and other unspecified scripts under plugins/BackUp/Archive/.

Cross-site scripting (XSS) vulnerability in wp-admin/edit-post-rows.php in WordPress 2.3 allows remote attackers to inject arbitrary web script or HTML via the posts_columns array parameter.

Cross-site scripting (XSS) vulnerability in wp-register.php in WordPress 2.0 and 2.0.1 allows remote attackers to inject arbitrary web script or HTML via the user_email parameter.

Cross-site scripting (XSS) vulnerability in wp-register.php in WordPress 2.0 allows remote attackers to inject arbitrary web script or HTML via the user_login parameter.

Multiple SQL injection vulnerabilities in Wordpress before 2.2.3 and Wordpress multi-user (MU) before 1.2.5a allow remote attackers to execute arbitrary SQL commands via the post_type parameter to the pingback.extensions.getPingbacks method in the XMLRPC interface, and other unspecified parameters related to "early database escaping" and missing validation of "query string like parameters."
