CVE-2018-19789

Priority
Description
An issue was discovered in Symfony 2.7.x before 2.7.50, 2.8.x before
2.8.49, 3.x before 3.4.20, 4.0.x before 4.0.15, 4.1.x before 4.1.9, and
4.2.x before 4.2.1. When using the scalar type hint `string` in a setter
method (e.g. `setName(string $name)`) of a class that's the `data_class` of
a form, and when a file upload is submitted to the corresponding field
instead of a normal text input, then `UploadedFile::__toString()` is called
which will then return and disclose the path of the uploaded file. If
combined with a local file inclusion issue in certain circumstances this
could escalate it to a Remote Code Execution.
