What is Pacemaker?

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

What is Wazuh?

Wazuh hardens its 4.14 line while 5.0 rebuilds how agents talk to the manager.

Wazuh ships 4.14 patch releases roughly every two to three weeks, and almost all of the content is security hardening: path traversal and command injection fixes, input validation in the cluster code, connection deadlines and memory leak fixes. 4.14.10 also added memory limits for oversized rulesets and queue warnings for the vulnerability scanner. In parallel, 5.0.0 reached its second release candidate on October 30.

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

◆ Current state

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

◆ Where it's heading

The cluster's internal transport is being rebuilt on the assumption that the network between nodes is not trusted. Authentication and encryption arrived first, and the fixes that followed, overflow guards and a maximum remote message size, are the hardening pass on the same code paths. Release discipline is heavy and visible: each version ships a release candidate with an identical commit set days earlier, and every 3.0 release documents the regressions it introduced and where they were fixed.

◆ Prediction

Remote CIB operations now support both X509 certificates and PSK, and the recent fixes all sit in message framing and size limits; further work is most likely to continue in that message-handling code rather than adding another authentication mechanism.

5.0

Wazuh hardens its 4.14 line while 5.0 rebuilds how agents talk to the manager.

◆ Current state

Wazuh ships 4.14 patch releases roughly every two to three weeks, and almost all of the content is security hardening: path traversal and command injection fixes, input validation in the cluster code, connection deadlines and memory leak fixes. 4.14.10 also added memory limits for oversized rulesets and queue warnings for the vulnerability scanner. In parallel, 5.0.0 reached its second release candidate on October 30.

◆ Where it's heading

5.0 is the real change: agents move to HTTPS for talking to the manager, a new detection engine replaces the 4.x analysis daemon, and every server install becomes a cluster node. The 4.14 branch, meanwhile, reads like a security audit being worked through release by release, which keeps current installs safe while 5.0 settles.

◆ Prediction

More 5.0 release candidates are likely before a final release, and 4.14 patch releases with security fixes should keep coming every few weeks; a 5.0 GA date is not stated in these entries.
