599eme Man has discovered a vulnerability in Free Arcade Script, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed via the "keyword" POST parameter to index.php (when "action" is set to "search") 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 versions 1.3 and 2.0. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised.
