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 Greenbone Vulnerability Manager?
Greenbone's scanner daemon is growing a web-application scanning class beside its network roots.
gvmd releases every week or two, and the changelog splits cleanly in three: a sustained build-out of web application scanning, a rewrite of how reports are modeled and exported, and a long tail of memory-management fixes in the C core. Recent versions added web application scanner preferences, scanner verification, and a Web Application VT subtype with a database migration. The report work moved from ad-hoc XML toward a structured report model addressable through new GMP commands.

Pacemaker

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.
Greenbone Vulnerability Manager
6.3INFRA · APIS
Greenbone's scanner daemon is growing a web-application scanning class beside its network roots.
◆ Current state
gvmd releases every week or two, and the changelog splits cleanly in three: a sustained build-out of web application scanning, a rewrite of how reports are modeled and exported, and a long tail of memory-management fixes in the C core. Recent versions added web application scanner preferences, scanner verification, and a Web Application VT subtype with a database migration. The report work moved from ad-hoc XML toward a structured report model addressable through new GMP commands.
◆ Where it's heading
Greenbone is widening what gvmd can orchestrate. Network and container scanning were the existing surface; web application scanning is being brought to parity, with its own VT class, preferences, validation, and verification path. In parallel the GMP protocol is gaining first-class report retrieval commands, which makes report data consumable by tooling rather than only renderable. The bug-fix stream is dominated by frees and cleanup in long-lived report paths, the signature of a codebase under memory pressure at scale.
◆ Prediction
Web Application VTs now have a subtype, a migration, and scanner verification, but the audit and scan report commands were added separately; expect the report model work to fold web application results into the same structured retrieval path rather than leaving a parallel one.
