Security readout for executives and security teams
Plain-English summary
This Jira Server and Data Center flaw can let an unauthenticated remote attacker learn names of private projects and private filters. The issue affects specific Jira 8.x ranges and is rated high because confidentiality loss is possible without login or user interaction.
Executive priority
Treat this as a high-priority confidentiality issue for exposed Jira systems. It is not described as code execution, but leaked private project and filter names can disclose sensitive business activity and support follow-on targeting.
Technical view
CVE-2021-41307 is an IDOR issue, CWE-639, in the Jira Workload Pie Chart Gadget. Affected versions are before 8.13.12 and 8.14.0 through before 8.20.0. CVSS 3.1 is 7.5: network exploitable, low complexity, no privileges, no user interaction, confidentiality impact high.
Likely exposure
Organizations running Atlassian Jira Server or Jira Data Center in the affected version ranges are exposed, especially if Jira is reachable by untrusted networks or anonymous users can access dashboards or gadgets.
Exploitation context
The source bundle provides no evidence of active exploitation and marks KEV false. The vulnerability is still operationally important because it is unauthenticated, remote, and can reveal private project and filter names.
Researcher notes
Evidence is limited to the CVE description and Atlassian reference. Do not assume broader data access beyond private project and private filter names. Validate affected version ranges and gadget exposure without using intrusive testing.
Mitigation direction
- Inventory Jira Server and Data Center versions.
- Prioritize systems in the affected version ranges.
- Move affected systems outside the vulnerable ranges per Atlassian guidance.
- Review Atlassian JRASERVER-72916 for official remediation details.
- Limit Jira exposure to trusted networks where feasible.
Validation and detection
- Confirm Jira version is not before 8.13.12.
- Confirm Jira 8.14.0 to before 8.20.0 is not deployed.
- Review anonymous access to dashboards and gadgets.
- Check whether private project or filter names were exposed.
- Document remediation evidence for vulnerability management records.
