PHP Debug Bar
PHP debug bar files were discovered.
The PHP debug bar is a PHP library that collects and presents debug information about PHP code, such as application state, performance, and values of passed variables. It can be used in a production environment to monitor the performance of the application, or in a development environment for debugging purposes.
An attacker can extract the values of variables such as user session, what is being executed on the server, what application is currently running etc.
Disabling the debug bar feature is highly recommended.
