phpunit >= 5.63 before 7.5.19 and 8.5.1 (this is a newly found vulnerability that is currently being submitted as a CVE after disclosure was provided to phpunit maintainers)

Patches

In the security patch, we look for the unwanted vendor/phpunit folder and remove it if we find it. This allows users to fix the security issue when upgrading.

Workarounds

Users can also simply remove the unwanted vendor/phpunit folder.
