Summary

zenstruck/collections is a set of helpers for iterating/paginating/filtering collections. Passing _callable strings_ (ie `system`) caused the function to be executed. This would result in a limited subset of specific user input being executed as if it were code. This issue has been addressed in commit `f4b1c48820` and included in release version 0.2.1. Users are advised to upgrade. Users unable to upgrade should ensure that user input is not passed to either `EntityRepository::find()` or `query()`.
