We do not support any old versions, all updates for bugs/features/security will be released in next planned version.

List of maintainers: https://checkstyle.org/team.html Mail-list for any questions: https://checkstyle.org/mailing-lists.html You can find admin emails in mail-list. You can find emails of maintainers in commits, you can clone our repo and see it by "git log".

If we are not responding, please keep pining us. As final resort, create an issue at https://github.com/checkstyle/checkstyle/issues with a note that you have a security issue.

If the vulnerability is accepted, we will create an issue (without much details) on Github Issue tracker and we put label "approved" on it. If the vulnerability is declined, we can keep it private or if you would like to keep record of it in issue tracker, you can do this also.
