Security readout for executives and security teams
Plain-English summary
This Jira Server and Data Center issue can expose user email addresses to anonymous remote users. It is not described as system takeover, but leaked emails can support phishing, account targeting, and privacy exposure. Prioritize externally reachable Jira instances first.
Executive priority
Treat as a moderate privacy and phishing-enablement risk. Schedule remediation through normal vulnerability management, accelerating for public Jira instances or environments with sensitive user populations.
Technical view
CVE-2021-39122 is an information disclosure flaw in Jira Server and Data Center where anonymous attackers may view user emails through the /rest/api/2/search endpoint. Affected ranges are before 8.5.13, 8.6.0 before 8.13.5, and 8.14.0 before 8.15.1.
Likely exposure
Exposure is most likely where affected Jira Server or Data Center versions are internet-accessible or reachable by untrusted users. The source bundle does not identify Jira Cloud as affected.
Exploitation context
The CVSS vector shows network access, low complexity, no privileges, and no user interaction. The bundle does not show CISA KEV listing or cited evidence of active exploitation.
Researcher notes
The provided record names the vulnerable endpoint and version ranges but does not include CWE, exploit evidence, or detailed workaround text. Keep analysis constrained to Jira Server and Data Center unless Atlassian expands scope.
Mitigation direction
- Upgrade affected Jira Server and Data Center versions beyond the vulnerable ranges.
- Check Atlassian guidance for any version-specific remediation or workaround.
- Limit anonymous and untrusted network access to Jira where business requirements allow.
- Review Jira user privacy and profile visibility settings.
Validation and detection
- Inventory Jira Server and Data Center versions across all environments.
- Identify instances below 8.5.13, 8.13.5, or 8.15.1 as applicable.
- Confirm whether anonymous access is enabled or externally reachable.
- Review logs for unusual anonymous search API activity.
