Hello Apache Kafka Team, In our product, kafka v4.3.0 is used. Below 2 Jline related vulnerabilities are reported on this kafka version - CVE-2026-56740 CVE-2026-56741 I see in kafka v4.3.0, jline-3.30.4.jar is present in the libs folder - libs/jline-3.30.4.jar/META-INF/maven/org.jline/jline-remote-telnet/pom.xml. As per github advisory, these vulnerabilities are fixed in Jline v4.2.1 versions. [1] CVE-2026-56740 Official Advisory - https://github.com/advisories/GHSA-47qp-hqvx-6r3f [2] CVE-2026-56741 Official Advisory - https://github.com/advisories/GHSA-2r2c-cx56-8933 Please confirm what apache kafka upcoming versions will upgrade to Jline v.4.2.1. Regards Vivek

In general, Kafka has a 1-year support window, so currently we are supporting 4.3, 4.2, and 4.1 release: https://kafka.apache.org/community/downloads/#supported-releases With the upcoming 4.4.0 release, 4.1 will drop out of the support window. So it's very unlikely that we would ship another 3.9.x bug-fix release. Given that 3.9 is the last release with ZK support, and upgrading to 4.x requires to migrate to KRaft, there is a possibility that we might maintain 3.9.x for a little longer than usual. However, officially 3.9 is not supported any longer, and the 3.9 and 4.0 release got archived already: https://kafka.apache.org/community/downloads/#archived-releases -Matthias On 8/19/26 7:21 AM, Gergely Harmadás wrote: > Hi James, > > I am not a project maintainer, just an enthusiastic contributor who > happened to have the same problem with lz4 :) There are some discussion > about a possible 3.9 release in this thread, so far no concrete...

Hi James, I am not a project maintainer, just an enthusiastic contributor who happened to have the same problem with lz4 :) There are some discussion about a possible 3.9 release in this thread, so far no concrete plans https://lists.apache.org/thread/bq27on99lf5b24d16zt5g5hnysd30c3w Best regards, Gergely On Mon, 17 Aug 2026 at 13:54, JAMES JOSE <jamejose@in.ibm.com> wrote: > Hello Gergely, > > Any plan for patching 3.9.* release with fixed version of lz4-java ? > > Regards, > James > > -----Original Message----- > From: JAMES JOSE > Sent: 17 August 2026 16:10 > To: 'users@kafka.apache.org' <users@kafka.apache.org> > Subject: RE: [EXTERNAL] Re: CVE-2026-59949 – Impact on Kafka (lz4-java) > > Thanks for the information. > > Regards, > James > > -----Original Message----- > From: Gergely Harmadás <harmadasg@gmail.com> > Sent: 14 August 2026 16:58 > To: users@k...

Hi, we have recently observed an increased amount of decreasing logappendtime events when the leader changed. It would be very helpful, if the logappendtime would never decrease for our use case. It seems possible to fix this with a minimal change by tracking the lastLogAppendTimeMs in the UnifiedLog.java and then force the now timestamp to be clamped with this lower bound. Is this something that we could contribute? thanks Alexander

Hello Gergely, Any plan for patching 3.9.* release with fixed version of lz4-java ?
