Summary

Dozzle is a realtime log viewer for docker containers. Prior to version 9.0.3, a flaw in Dozzle’s agent-backed shell endpoints allows a user restricted by label filters (for example, `label=env=dev`) to obtain an interactive root shell in out‑of‑scope containers (for example, `env=prod`) on the same agent host by directly targeting their container IDs. Version 9.0.3 contains a patch for the issue.
