Rating-Widget: Star Review System allows anybody to turn on debug mode and view errors and warnings

The plugin allows anybody to turn on debug mode and view errors and warnings. Errors and warnings should be turned off on production sites as they reveal information useful to attackers such as paths, and may give hints as to how themes and plugins are written.

Proof of concept

Add 1/0; to functions.php in the theme
Enable this plugin
Visit http://localhost/?rwdbg=true
(You may need to view source, depending on the theme)
You will see a PHP warning, including the path to your functions.php file

Upgrade to version 2.9.0 or later.
