CakePHP: View::element() is missing a path containment check

CakePHP is a rapid development framework for PHP. In versions 4.5.11 and earlier, 4.6.0 through 4.6.3, 5.0.0 through 5.1.6, 5.2.0 through 5.2.12, and 5.3.0 through 5.3.5, View::_getElementFileName() does not check that the resolved element path is within the application/plugin view template paths. When element names are created with specifically crafted user-supplied data this weakness can be leveraged to include other PHP files on the server. Patched releases are available in 5.3.6, 5.2.13, 5.1.7, 4.6.4, and 4.5.11.
