Context & Problem
Dependabot alert for io.netty:netty-codec-http flagged a CORS Vary Header Overwrite cache poisoning/information disclosure vulnerability (GHSA-8c42-7qj2-3j46) affecting versions >= 4.2.0.Final and <= 4.2.16.Final. This vulnerability is fixed in io.netty 4.2.17.Final.
USPR-13904
Solution
Updated the existing Gradle resolutionStrategy override in root build.gradle that forces io.netty dependency versions to a minimum of 4.2.17.Final (previously 4.2.16.Final). This matches the established pattern for managing Netty CVEs in the repository.
