## Overview

Azkaban through 4.0.0 omits project permission checks in the ScheduleServlet fetchSchedule action, allowing authenticated users to read any project's schedule configuration. Attackers can supply arbitrary project and flow identifiers to retrieve sensitive schedule details including execution times, cron expressions, flow parameters, and notification email lists without proper authorization.
