Description
My anchore scan picked up this CVE on data-prepper's latest docker image. Reporting this for due diligence, as this would constitute as a prod-blocking finding if we had SSL enabled on our test systems.

As far as I can tell, this issue is fixed in Netty 4.1.137.Final and 4.2.17.Final

Start by locating Data Prepper's Netty dependency declarations and the Docker image build configuration, then compare the resolved Netty version with 4.1.137.Final or 4.2.17.Final. Rebuild the latest image and rerun an Anchore vulnerability scan; done means CVE-2026-75595 and the listed related findings are no longer reported.
