Unrestricted file upload vulnerability in WordPress 2.5.1 and earlier might allow remote authenticated administrators to upload and execute arbitrary PHP files via the Upload section in the Write Tabs area of the dashboard.
wp-includes/vars.php in Wordpress before 2.2.3 does not properly extract the current path from the PATH_INFO ($PHP_SELF), which allows remote attackers to bypass intended access restrictions for certain pages.
The cookie authentication method in WordPress 2.5 relies on a hash of a concatenated string containing USERNAME and EXPIRY_TIME, which allows remote attackers to forge cookies by registering a username that results in the same concatenated string, as demonstrated by registering usernames beginning with "admin" to obtain administrator privileges, aka a "cryptographic splicing" issue. NOTE: this vulnerability exists because of an incomplete fix for CVE-2007-6013.
SQL injection vulnerability in ss_load.php in the Spreadsheet (wpSS) 0.6 and earlier plugin for WordPress allows remote attackers to execute arbitrary SQL commands via the ss_id parameter.
Multiple cross-site scripting (XSS) vulnerabilities in WordPress 2.3.2 allow remote attackers to inject arbitrary web script or HTML via the (1) inviteemail parameter in an invite action to wp-admin/users.php and the (2) to parameter in a sent action to wp-admin/invites.php.
The XML-RPC implementation (xmlrpc.php) in WordPress before 2.3.3, when registration is enabled, allows remote attackers to edit posts of other blog users via unknown vectors.
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.
