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.

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

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.

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.

SQL injection vulnerability in WordPress 1.5.2, and possibly other versions before 2.0, allows remote attackers to execute arbitrary SQL commands via the User-Agent field in an HTTP header for a comment.

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.

wp-admin/setup-config.php in the installation component in WordPress 3.3.1 and earlier generates different error messages for requests lacking a dbname parameter depending on whether the MySQL credentials are valid, which makes it easier for remote attackers to conduct brute-force attacks via a series of requests with different uname and pwd parameters. NOTE: the vendor disputes the significance of this issue; also, it is unclear whether providing intentionally vague error messages during installation would be reasonable from a usability perspective

wp-admin/setup-config.php in the installation component in WordPress 3.3.1 and earlier does not ensure that the specified MySQL database service is appropriate, which allows remote attackers to configure an arbitrary database via the dbhost and dbname parameters, and subsequently conduct static code injection and cross-site scripting (XSS) attacks via (1) an HTTP request or (2) a MySQL query. NOTE: the vendor disputes the significance of this issue; however, remote code execution makes the issue important in many realistic environments

Cross-site scripting (XSS) vulnerability in lanoba-social-plugin/index.php in the Lanoba Social plugin 1.0 for WordPress allows remote attackers to inject arbitrary web script or HTML via the action parameter. NOTE: the vendor disputes this issue, stating "Lanoba's plug in does sanitize user input, and because that input is never sent to the browser, an attacker has no way of executing script or code on a user's behalf.

NOTE: the vendor disputes the significance of this issue; also, it is unclear whether this specific XSS scenario has security relevance

wp-admin/setup-config.php in the installation component in WordPress 3.3.1 and earlier does not limit the number of MySQL queries sent to external MySQL database servers, which allows remote attackers to use WordPress as a proxy for brute-force attacks or denial of service attacks via the dbhost parameter, a different vulnerability than CVE-2011-4898. NOTE: the vendor disputes the significance of this issue because an incomplete WordPress installation might be present on the network for only a short time

The wp_create_nonce function in wp-includes/pluggable.php in WordPress 3.3.1 and earlier associates a nonce with a user account instead of a user session, which might make it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks on specific actions and objects by sniffing the network, as demonstrated by attacks against the wp-admin/admin-ajax.php and wp-admin/user-new.php scripts. NOTE: the vendor reportedly disputes the significance of this issue because wp_create_nonce operates as intended, even if it is arguably inconsistent with certain CSRF protection details advocated by external organizations

WordPress through 4.8.2 uses a weak MD5-based password hashing algorithm, which makes it easier for attackers to determine cleartext values by leveraging access to the hash values. NOTE: the approach to changing this may not be fully compatible with certain use cases, such as migration of a WordPress site from a web host that uses a recent PHP version to a different web host that uses PHP 5.2. These use cases are plausible (but very unlikely) based on statistics showing widespread deployment of WordPress with obsolete PHP versions.

The XMLRPC API in WordPress before 3.5.1 allows remote attackers to send HTTP requests to intranet servers, and conduct port-scanning attacks, by specifying a crafted source URL for a pingback, related to a Server-Side Request Forgery (SSRF) issue.
