In Symfony before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, it is possible to cache objects that may contain bad user input. On serialization or unserialization, this could result in the deletion of files that the current user has access to. This is related to symfony/cache and symfony/phpunit-bridge.
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
