Dozzle is a realtime log viewer for docker containers. Prior to 10.6.7, streamEvents in internal/web/events.go applies a restricted user's label filter to container lists but not to the container-stat and container-event channels returned by GET /api/events/stream. In a simple-auth deployment using per-user filters, any authenticated restricted account can receive resource telemetry and lifecycle events for containers outside its authorized label scope. The exposed data includes container names, images, full label maps, CPU and memory use, network and disk totals, and deployment or restart activity across monitored hosts, but does not include log contents, environment values, or exec access.
This issue is fixed in version 10.6.7.
