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 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 sidebar.php in WordPress, when custom 404 pages that call get_sidebar are used, allows remote attackers to inject arbitrary web script or HTML via the query string (PHP_SELF), a different vulnerability than CVE-2007-1622.
