Jason St-Cyr — Thu, 09 Apr 2026 12:06:38 +0000

You can now download Puppet Core 8.18.0! This update adds support for macOS 15 and includes several important security updates to help keep your infrastructure protected.

As always, Puppet Core releases focus on stability, platform support, and staying ahead of reported vulnerabilities.

👉 Official Puppet Core 8.18 release notes

What’s new in Puppet Core 8.18.0

Support for macOS 15: Puppet Core now supports macOS 15 on both x86_64 and ARM architectures. This enables continued management of macOS systems using the same automation controls and policies you already rely on.

Security focused dependency updates

Security remains a top priority in every Puppet Core release. This release includes updates to several bundled components to address recently disclosed security vulnerabilities. By delivering these updates as part of hardened Puppet Core builds, you reduce dependency risk without tracking, validating, or rebuilding components independently.

🔐 libxml2 updated

libxml2 has been updated to version 2.15.2
Addresses the following CVEs:
- CVE-2026-0989
- CVE-2026-0990
- CVE-2026-0992
- CVE-2026-1757

🔐 zlib gem updated

zlib gem updated to version 3.0.1
Addresses:
- CVE-2026-27820

🔐 curl updated

curl updated to version 8.19.0
Addresses:
- CVE-2026-1965
- CVE-2026-3783
- CVE-2026-3784
- CVE-2026-3805

If you rely on Puppet Core in security‑sensitive or regulated environments, this release is strongly recommended.

Getting Puppet Core 8.18.0

You can upgrade to Puppet Core 8.18.0 using your existing Puppet Core repositories and standard upgrade workflows. Upgrading to Puppet Core 8.18.0 helps you take advantage of the latest platform support, reduce exposure to dependency related security risk, and rely on vendor-tested packages instead of managing updates yourself.

As always:

Test upgrades in a staging environment first
Review the full release notes for platform‑specific details
Roll out broadly once validated

📄 Puppet Core Installation Docs:

Let us know how it goes

If you’re upgrading to 8.18.0, running Puppet Core on macOS 15, or have feedback on this release, let us know in the comments. Your input helps shape future updates.

Happy puppeting!

Puppetlabs Modules Roundup – March 2026

Jason St-Cyr — Mon, 06 Apr 2026 14:24:03 +0000

March 2026 brought 4 Puppetlabs module releases in the Puppetlabs Forge catalog. Read along to see what changed this month!

Across the month, the clearest themes were compatibility updates across Puppet Enterprise (PE), supported platforms, and operational hardening and troubleshooting improvements.

Highlighted Updates

Compatibility updates across PE and supported platforms

March releases leaned toward version-alignment work, with updates for newer Puppet Enterprise releases, Ubuntu 24.04 benchmark coverage, and dependency ranges that allow newer supporting modules.

Added support for PE 2023.8.9 and 2025.9.0.
Added CIS Benchmark support for Ubuntu 24.04 Server Levels 1 and 2.

Operational hardening and troubleshooting improvements

Several releases focused on making "Day Two" operations safer and easier to debug through better validation, more useful logging, and targeted runtime fixes.

Added installer untar checks and deduplicated hosts in the legacy compiler group.
Moved most SCE-specific logging into the Puppet agent run log for easier debugging.

Puppet Enterprise 2025.10 Resolves Malformed Task and Plan Metadata Failures

Jason St-Cyr — Tue, 31 Mar 2026 18:28:46 +0000

We’ve released a patch in Puppet Enterprise 2025.10 to resolve an issue affecting task and plan metadata handling.

Prior to PE 2025.9: Malformed task or plan metadata was logged in the bolt-server log, and the affected task or plan was ignored. Other tasks and plans continued to work as expected.

In PE 2025.9: Malformed metadata caused the task and plan listing to fail to load entirely and prevented affected tasks or plans from running. Errors were written to the bolt-server log.

With PE 2025.10: Task and plans retain the improvements from 2025.9 but will now also load correctly even when malformed metadata is present.

Puppet Enterprise 2025.9 and 2023.8.9 are available!

Jason St-Cyr — Wed, 25 Mar 2026 13:24:08 +0000

Puppet Enterprise 2025.9 and 2023.8.9 are now available, delivering improved operational visibility, expanded agent platform support, and important security fixes for both the latest and 2023.8 LTS streams.

What's new in PE 2025.9?

In Puppet Enterprise 2025.9, this release improves day-to-day operations with:

Real-time visibility into Advanced Patching runs directly in the PE console
Clearer error and warning messages when patch group creation fails, plus retry support from the console or API
The ability to edit workflows and stop running workflows from the PE console or via API
Agent support for Debian 13 on amd64 and aarch64
Multiple CVEs addressed, along with fixes to Advanced Patching behavior and Infra Assistant reliability

What's new in PE 2025.8.9?

🔔Lifecycle Reminder

Ubuntu 24.04 support comes to Puppet SCE for Linux

Jason St-Cyr — Wed, 18 Mar 2026 17:52:28 +0000

The latest 2.6.0 version of Puppet Security Compliance Enforcement (SCE) for Linux is now available. This release adds support for Ubuntu 24.04 LTS and includes a few operational improvements aimed at making SCE easier to run and troubleshoot in day‑to‑day Puppet environments.

Below is a quick overview of what’s new.

Ubuntu 24.04 LTS support

One of the main additions in this release is support for Ubuntu 24.04 LTS. SCE for Linux now allows you to enforce the CIS benchmarks v1.0.0 on Ubuntu 24.04 systems. Both Level 1 and Level 2 CIS profiles are supported.

Operational improvements

This release also includes some changes intended to improve visibility and troubleshooting.

Logging changes

Most SCE logs are now written to the Puppet agent run log. This means you can get more insight into SCE behavior by running the Puppet agent in debug mode, rather than checking separate log locations.

Updated mount information fact

The custom fact sce_mount_info has been updated to report information about all mounted file systems, providing a more complete view of the system during enforcement.

Updated Puppet module dependencies

SCE for Linux now supports the latest versions of puppet/systemd, puppet/logrotate, and puppetlabs/augeas_core.

Resolved issues

Puppet runs no longer fail on systems where the rsyslog package is not installed. This helps avoid unnecessary failures on minimal or customized Linux images.
Unnecessary PAM_POSITION_ALIASES warning messages related to the augeasproviders_pam module should no longer display.

More details
