Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system.
Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery".
Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.
Ryuzaki Lawlet has reported two vulnerabilities in the Yahoo Answer WordPress Auto Poster plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the "catname" parameter to process-imported-question.php and the "query" parameter to editautopilot.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Edit the source code to ensure that input is properly sanitised.
