Incident Response Checklist 🚨 Immediate Actions (0-24 hours) Notify all relevant stakeholders about the vulnerability and potential impact. Apply the recommended patches to Jira Software versions 9.12.28, 10.3.12, or 11.1.0 immediately. Restrict JVM filesystem permissions to limit write access. Segment network access to Jira instances to minimize exposure. Enable anomaly detection for unauthorized file changes. 🔄 Recovery Actions Restore affected files and configurations from known-good backups. Rebuild compromised systems if integrity cannot be assured. Reinforce security controls around Jira instances post-recovery. Conduct a full system audit post-recovery to ensure no residual vulnerabilities.
