    Field note · TruePositive EditorialCurated

    This is confirmed exploited in the wild. It is in the CISA KEV catalog, so attackers are actively using it, not just researchers. It is reachable over the network with no authentication and no user interaction, which is the most dangerous profile. Patch this on priority and confirm the fix holds.

  • 0
    Remediation · TruePositive EditorialCurated

    Required action for Oracle Java Runtime Environment (JRE): Apply updates per vendor instructions. CISA set a federal remediation due date of 2022-06-15. After patching, verify the vulnerable path is no longer reachable before closing the finding.
