Security readout for executives and security teams
Plain-English summary
This Jira flaw could let an unauthenticated remote person learn names of private projects and filters. That may expose sensitive business, customer, or security program context even without data modification. The supplied sources identify Jira Server and Data Center versions before 8.13.12 as affected.
Executive priority
Treat as high priority where Jira is exposed to the internet or contains sensitive project names. The issue leaks metadata, not full project content, but private names can reveal customers, incidents, internal initiatives, or security work.
Technical view
CVE-2021-41305 is a CWE-639 IDOR in Jira Server/Data Center's Average Number of Times in Status Gadget. CVSS 3.1 is 7.5: network reachable, low complexity, no privileges, no user interaction, high confidentiality impact, no integrity or availability impact.
Likely exposure
Exposure is most relevant for internet-accessible or broadly reachable Jira Server/Data Center deployments running versions before 8.13.12, especially where anonymous users can reach dashboard gadgets.
Exploitation context
The supplied bundle does not establish active exploitation. CISA KEV status is false, and the cited sources only describe the vulnerability and affected product/version boundary.
Researcher notes
Evidence is limited to the CVE record and Atlassian issue reference. The source bundle names the vulnerable gadget and fixed boundary before 8.13.12, but does not provide exploit telemetry or a broader version matrix.
Mitigation direction
- Upgrade affected Jira Server/Data Center deployments to 8.13.12 or later per Atlassian guidance.
- Confirm all externally reachable Jira instances are inventoried and version-checked.
- Review anonymous access settings for Jira dashboards and gadgets.
- If upgrade is delayed, consult Atlassian guidance for supported temporary mitigations.
Validation and detection
- Identify Jira Server and Data Center instances and record exact versions.
- Flag any deployment running before 8.13.12 as potentially affected.
- Review whether anonymous users can reach dashboards or gadgets.
- Check logs for unusual anonymous access to Jira gadget or dashboard resources.
