We’ve just now published new CrateDB releases for all 5.2, 5.3, 5.4 and 5.5 versions to the testing channels which contain the related fix.


As the discoverer of this vulnerability, I think Cratedb’s timely repair measures and responsible disclosure policy are excellent.


Dear @Tu0Laj1,

first of all, thank you for reporting the flaw to us.

However, handling the responsible disclosure well would have initially been your obligation. Please try to reach out to the vendor next time before you will publish a security vulnerability in the open. This is what responsible disclosure is all about.

With kind regards,

First of all, I apologize because I did not find a specific channel to provide feedback on security vulnerabilities in a prominent location on the GitHub of Cratedb. Someone has previously inquired about this issue: List of CVE in Crate DB · Issue #15172 · crate/crate · GitHub

Thank you for your feedback. We will try to improve the discoverability how to report security incidents to us, by making it more prominent.

Adding a security vulnerability feedback method to the README file of the github in Cratedb is a good way, isn’t it, or
