["Ryan Skraba (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-23542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17825712#comment-17825712 ] 

Ryan Skraba commented on FLINK-23542:
-------------------------------------

This has become slightly more important : the last version of the CheckStyle-IDEA plugin we use in IntelliJ dropped support for 8.x in March 2024 [https://github.com/jshiell/checkstyle-idea/releases/tag/5.88.0]

New Flink developers or existing developers keeping their IDE and plugins up to date won't be able to use the existing checkstyle configuration.

> Checkstyle version < 8.29 are still vulnerable to XML External Entity (XXE) Processing due to an incomplete fix for CVE-2019-9658.
> {noformat}
> Impact
> User: Build Maintainers
> This vulnerability probably doesn't impact Maven/Gradle users as, in most cases, these builds are processing files that are trusted, or pre-vetted by a pull request reviewer before being run on internal CI infrastructure.
