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 Velociraptor?

Velociraptor's recent releases are mostly about patching CVEs.

Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.

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.

0.0

Velociraptor's recent releases are mostly about patching CVEs.

◆ Current state

Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.

◆ Where it's heading

Since June the project has been in security mode, fixing CVEs on the current line and backporting to the previous one. Feature work shows up as new artifacts, here an Azure Monitor export, which keeps Velociraptor feeding results into the logging tools teams already use.

◆ Prediction

Expect further 0.77 patch releases and possibly another backport if new CVEs are published; the timing of a 0.78 feature release is not signaled here.
