CVE-2019-10912
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
