Data Leak

A data leak is the publication of unwanted information, which leads to further security attack, or actual data theft.

A data leak may be both a successful breach, when it collect directly usable information, such as reading private information; it may also be a stepping stone for a following and more complex attack, such as identifying the PHP version or the underlying framework.
