sullo has reported some vulnerabilities in Unobtrusive Ajax Star Rating Bar, which can be exploited by malicious people to bypass certain security restrictions or conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "q" and "t" variables in rpc.php and db.php is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "q" variable in rpc.php is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

3) Input passed to the "HTTP_REFERER" variable in db.php is not properly sanitised before being used. This can be exploited to e.g. bypass certain restrictions via CRLF character sequences and inject arbitrary HTTP headers and HTTP body data in a request.

Solution
Update to version 1.2.0 or later.
