Ufuk's summary is correct.There's a slight caveat in that we'd also have to bump the shade-plugin to 3.1.1 since it otherwise fails on jackson,but I have no concerns about this change.

As far as I can tell, the next steps would be: 1) Release flink-shaded with upgraded Jackson 2a) Bump the flink-shaded version by default in master2b) Create opt-in profiles for 1.8 and 1.9 (the opt-in profiles should alsocover the upgrade to the most recent flink-shaded version) @Chesnay: is this a correct summary?Note this would block the 1.8.3 release on step 1. As an upside, we might get some additional feedback until the 1.10 release with these profiles incase users make use of them with 1.8/1.9. – Ufuk On Fri, Nov 15, 2019 at 12:08 PM Chesnay Schepler <ches...@apache.org> wrote:The opt-in approach would only be used for 1.8.3 / 1.9.2; on master (andthus starting from 1.10.0) it's not opt-in. I have only proposed it as an opt-in because a) we usually do not bump dependencies in bugfix releases and b) it's a short-term change that we aren't allowing to mature properly. In contrast, the 1.10 release is significantly further away, hence no opt-in. Hence, I'm not concerned about such kind of ugprades being more common in the future. We can certainly support every jackson version that fixes these vulnerabilities; individual modules can always use a different version (that hopefully includes the fixes). Ideally of course we'd only be using 1 version, but that may or may not be feasible. On 15/11/2019 04:07, Hequn Cheng wrote:Hi Chesnay, Great to hear that jackson-2.10.1 works well on master. Really a goodjob!- Whether backport this change to 1.8/1.9 I had taken a quick look at the security vulnerabilities, some of them seem can lead to high-security problems, thus from my point of view, I'm in favor of adding the fix into 1.9/1.8. However, I would like to trust your judgment as you are more professional at this problem. - How to port this change to 1.8/1.9 I think providing an opt-in upgrade is a good idea. Another question here is whether do we plan to support multi jackson versions that have eliminated the security vulnerabilities. If we only plan to support 2.10.1, I would like to make it a non-opt-in upgrade. As an option, users can downgrade the flink version if meet problems using the new version. Of course, we will try our best to make the new release out of question. Another concern of making it an opt-in upgrade is, it will make our build unlikely convergence as more and more build options will be added when we upgrade a commonly used lib like this one. What do you think?

The flink master works perfectly fine with that version; 1.9 will likely do so too and 1.8 would require a minor adjustment.Hence, there may be value in first doing a flink-shaded release sowe can eliminate these vulnerabilities in 1.8.3 and 1.9.2 . As for other jackson dependencies (coming from calcite, kafka, kinesis), I ran the unit and end-to-end tests of master yesterday will /all /jackson dependencies set to 2.10.1, and they passed. I will open a PR soon-ish for making this change on master. The question now is whether we want to backport this change to 1.8/1.9 . Some code paths /may /not be covered by our tests, and transitive jackson users /might /run into issues. Alternatively, we could set this up as an opt-in upgrade, by adding a separate profile that bumps the versions. This would present users/providers who are concerned about the vulnerabilities an easy workaround, at the risk of /some /things /maybe /not working.

We already have many important bug fixes in the release-1.8branch (29resolved issues).
