Discussion

WordPress KSES Library Multiple HTML Injection Vulnerabilities

WordPress is prone to multiple HTML-injection vulnerabilities because it fails to properly sanitize user-supplied input.

Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.

Versions prior to WordPress 3.0.4 are vulnerable.
