wp-admin/admin.php in WordPress and WordPress MU before 2.8.1 does not require administrative authentication to access the configuration of a plugin, which allows remote attackers to specify a configuration file in the page parameter to obtain sensitive information or modify this file, as demonstrated by the (1) collapsing-archives/options.txt, (2) akismet/readme.txt, (3) related-ways-to-take-action/options.php, (4) wp-security-scan/securityscan.php, and (5) wp-ids/ids-admin.php files. NOTE: this can be leveraged for cross-site scripting (XSS) and denial of service.

The forgotten mail interface in WordPress and WordPress MU before 2.8.1 exhibits different behavior for a password request depending on whether the user account exists, which allows remote attackers to enumerate valid usernames. NOTE: the vendor reportedly disputes the significance of this issue, indicating that the behavior exists for "user convenience."

WordPress and WordPress MU before 2.8.1 exhibit different behavior for a failed login attempt depending on whether the user account exists, which allows remote attackers to enumerate valid usernames. NOTE: the vendor reportedly disputes the significance of this issue, indicating that the behavior exists for "user convenience."

PHP remote file inclusion vulnerability in firestats-wordpress.php in the FireStats plugin before 1.6.2-stable for WordPress allows remote attackers to execute arbitrary PHP code via a URL in the fs_javascript parameter.

SQL injection vulnerability in the FireStats plugin before 1.6.2-stable for WordPress allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

SQL injection vulnerability in viewimg.php in the Paolo Palmonari Photoracer plugin 1.0 for WordPress allows remote attackers to execute arbitrary SQL commands via the id parameter.

SQL injection vulnerability in fmoblog.php in the fMoblog plugin 2.1 for WordPress allows remote attackers to execute arbitrary SQL commands via the id parameter to index.php. NOTE: some of these details are obtained from third party information.

WordPress before 2.6.2 does not properly handle MySQL warnings about insertion of username strings that exceed the maximum column width of the user_login column, and does not properly handle space characters when comparing usernames, which allows remote attackers to change an arbitrary user's password to a random value by registering a similar username and then requesting a password reset, related to a "SQL column truncation vulnerability." NOTE: the attacker can discover the random password by also exploiting CVE-2008-4107.

The (1) get_edit_post_link and (2) get_edit_comment_link functions in wp-includes/link-template.php in WordPress before 2.6.1 do not force SSL communication in the intended situations, which might allow remote attackers to gain administrative access by sniffing the network for a cookie.

Cross-site scripting (XSS) vulnerability in WordPress before 2.6, SVN development versions only, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
