CVE-2021-41112Network attack vector

Scheduled job disruption via unauthorized calendar changes

Published Feb 28, 2022 · Updated Apr 23, 2025

Missing authorization in Rundeck before 3.4.5 allows remote authenticated users to alter calendars and disrupt scheduled job timing. Calendar modification and deletion paths process requests without checking whether the user's roles authorize changes to System or Project calendars. Any authenticated account can change or remove calendar rules, causing governed jobs to run or be skipped on affected dates.
