- Issue
- 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.
Recommended action: Upgrade to 4.2.7, 4.1.12, 3.4.26 or 2.8.50 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
