DESCRIPTION:
High-Tech Bridge SA has discovered a vulnerability in the Fast Secure
Contact Form plugin for WordPress, which can be exploited by malicious
people to conduct cross-site scripting attacks.

Input appended to the URL after
wp-content/plugins/si-contact-form/captcha/test/index.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.

The vulnerability is confirmed in version 3.0.3.1. Prior versions may
also be affected.

SOLUTION:
Update to version 3.0.3.2.
