A vulnerability has been reported in the Artiss Code Embed plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed via the "suffix" parameter to wp-admin/admin.php (when "page" is set to "ace-search") is not properly sanitised in wp-content/plugins/simple-embed-code/includes/ace-search.php 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.

The vulnerability is reported in versions prior to 2.0.2.

Solution
Update to version 2.0.2.
