While we are working to upgrade the affected dependencies of all
components, we recommend users follow the advisory of the Apache
Log4j
Community. Also Ververica platform can be patched with a similar
approach:
To configure the JVMs used by Ververica Platform, you can pass custom
Java options via the JAVA_TOOL_OPTIONS environment variable. Add the
following to your platform values.yaml, or append to the existing
value
of JAVA_TOOL_OPTIONS if you are using it already there, then redeploy
the platform with Helm:
env:
- name: JAVA_TOOL_OPTIONS
value: -Dlog4j2.formatMsgNoLookups=true
For any questions, please contact us via our support portal.

Timo
