Hi all,

Ignition 8.3.4 comes bundled with Azul Zulu Java 17.62.18 from what I understand. Our security scans picked up several possible vulnerabilities in this version and our IT-Security departments advised us to upgrade. As this effects all gateways and all clients with designer installed, a manual replacement on all machines with the config edits described here [Upgrading Zulu OpenJDK for the Designer - Ignition - Inductive Automation Forum](https://forum.inductiveautomation.com/t/upgrading-zulu-openjdk-for-the-designer/110542/2) would be extremely time consuming.

The reported CVEs are CVE-2025-6052, CVE-2025-6021, CVE-2025-7425, CVE-2025-43368, and CVE-2025-47219. I couldn't find any information on these CVEs in Inductive Automation Trust Center.

Could you please point me to resources on how to mitigate these vulnerabilities?

Thank you

These CVEs don't present an immediate risk to Ignition users.

Ignition 8.3.5 includes an updated Java runtime that has resolved these issues. Upgrading to 8.3.5 as soon as it's available would be the easiest path.
