Security readout for executives and security teams

CVE-2021-26078 is a cross-site scripting issue in Atlassian Jira Server and Jira Data Center. A remote attacker could inject HTML or JavaScript through the number range searcher component. The bundle does not provide CVSS scoring or evidence of active exploitation. Exposure is most likely for organizations running self-managed Jira Server or Jira Data Center in the affected version ranges, especially where untrusted users can interact with issue search or related number range search fields. Treat as a standard security patching priority for self-managed Jira. It is not KEV-listed in the bundle, but Jira often holds sensitive operational data, so affected internet-facing systems should be updated promptly. Mitigation focus: Upgrade Jira Server or Data Center to 8.5.14, 8.13.6, 8.16.1, or later supported versions.; Review Atlassian advisory JRASERVER-72392 for official fix and deployment guidance.; Restrict Jira access to trusted users and networks until affected instances are upgraded..
