Security readout for executives and security teams
Plain-English summary
Rundeck before 3.4.5 let logged-in users change or delete system or project calendars without proper permission checks. Those calendars can control when scheduled jobs run, so misuse could make important automation run on the wrong days or fail to run when needed.
Executive priority
Treat as high priority for Rundeck environments running business-critical automation. The issue does not expose data directly, but it can affect integrity and availability of scheduled operations. Upgrade planning should be prompt, especially where many users can authenticate to Rundeck.
Technical view
CVE-2021-41112 is a missing authorization flaw (CWE-862) in Rundeck versions before 3.4.5. Authenticated users could modify or delete System or Project level Calendars without appropriate authorization. CVSS 3.1 is 8.1, driven by low attack complexity, low privileges required, and high integrity and availability impact.
Likely exposure
Exposure is limited to Rundeck deployments earlier than 3.4.5 where untrusted or broadly provisioned authenticated users can access the service. Business risk depends on what scheduled jobs are controlled by affected calendar definitions.
Exploitation context
The provided sources do not report known active exploitation, and the CVE is not marked as CISA KEV. The issue requires authentication, but no user interaction. The practical impact is disruption or manipulation of scheduled automation through unauthorized calendar changes.
Researcher notes
Focus review on authorization enforcement around System and Project level Calendar modification and deletion paths. The source bundle names no workaround and provides no exploit evidence. Avoid assuming unauthenticated reachability or broader product impact beyond Rundeck before 3.4.5.
Mitigation direction
- Upgrade Rundeck to version 3.4.5 or later.
- If immediate upgrade is blocked, check current vendor guidance; sources list no workaround.
- Restrict Rundeck access to trusted users until patched.
- Review permissions for users with access to automation scheduling features.
Validation and detection
- Inventory Rundeck instances and confirm installed versions.
- Verify any instance below 3.4.5 is prioritized for upgrade.
- Review audit logs for unexpected calendar modifications or deletions.
- Identify scheduled jobs governed by System or Project calendars.
- Confirm post-upgrade calendar authorization behavior matches expected permissions.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
