Note: Versions mentioned in the description apply only to the upstream kube-fluentd-operator package and not the kube-fluentd-operator package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, Rack::Directory’s path check used a string prefix match on the expanded path. A request like /../root_example/ can escape the configured root if the target path starts with the root string, allowing directory listing outside the intended root. Versions 2.2.22, 3.1.20, and 3.2.5 fix the issue.
