CVE-2019-10912 (opens in a new tab)How to fix?
Upgrade Debian:12 symfony to version 3.4.22+dfsg-2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream symfony package and not the symfony package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
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.
