What is OpenTofu?

OpenTofu's v1.13 beta puts user-defined functions and types into the language for the first time.

The v1.11 series has just been closed out with a final patch, and the feed's recent history is almost entirely security work: an OCI credential leak on redirect, an init denial-of-service via crafted registry URLs, an ECH pre-shared-key leak, an arbitrary file read. Against that, v1.13.0-beta1 opens a new series with two experiments — Symbol Libraries and a -lint flag — alongside a substantial list of breaking changes.

What is Slurm?

Slurm coordinated a 7-CVE security drop across three active branches, including a privilege escalation and SQL injection.

Slurm released coordinated security patches across three active branches (25.05.x, 25.11.x, 26.05.x) fixing 7-8 CVEs per branch: sbcast credential bypass (CVE-2026-65107), slurmstepd stack overflow via SPANK environment variables (CVE-2026-65108), OCI container directory traversal (CVE-2026-65109), heap over-read in forward data RPC (CVE-2026-65138), SQL injection via cluster names in accounting queries (CVE-2026-65139), operator-to-administrator privilege escalation (CVE-2026-65140), and step distribution issues (CVE-2026-65165). The 26.05.3 patch also added support for external nodes in heterogeneous jobs — a meaningful expansion for cloud-burst HPC workflows.

OpenTofu's v1.13 beta puts user-defined functions and types into the language for the first time.

◆ Current state

The v1.11 series has just been closed out with a final patch, and the feed's recent history is almost entirely security work: an OCI credential leak on redirect, an init denial-of-service via crafted registry URLs, an ECH pre-shared-key leak, an arbitrary file read. Against that, v1.13.0-beta1 opens a new series with two experiments — Symbol Libraries and a -lint flag — alongside a substantial list of breaking changes.

◆ Where it's heading

Symbol Libraries are the first release here that changes what a configuration author can express rather than what the tool does with the configuration. The beta also spends a real compatibility budget to get there: WinRM provisioner connections removed, base64gzip output changed, macOS 13 required, 32-bit builds ending. Everything else in the window — the KMS provider arguments, the OCI credential scoping, the plan-file schema embedding — is the maintenance and supply-chain hardening a fork has to do to be trusted as a drop-in.

◆ Prediction

Both new capabilities ship as experiments explicitly seeking feedback before stabilising, so the v1.13 series is likely to iterate on Symbol Library syntax and linting rules ahead of a stable release rather than adding another language feature.

5.0

Slurm coordinated a 7-CVE security drop across three active branches, including a privilege escalation and SQL injection.

◆ Current state

Slurm released coordinated security patches across three active branches (25.05.x, 25.11.x, 26.05.x) fixing 7-8 CVEs per branch: sbcast credential bypass (CVE-2026-65107), slurmstepd stack overflow via SPANK environment variables (CVE-2026-65108), OCI container directory traversal (CVE-2026-65109), heap over-read in forward data RPC (CVE-2026-65138), SQL injection via cluster names in accounting queries (CVE-2026-65139), operator-to-administrator privilege escalation (CVE-2026-65140), and step distribution issues (CVE-2026-65165). The 26.05.3 patch also added support for external nodes in heterogeneous jobs — a meaningful expansion for cloud-burst HPC workflows.

◆ Where it's heading

Slurm's three-branch maintenance model reflects the reality of HPC deployments: clusters running critical workloads don't upgrade quickly, so SchedMD backports security fixes to older release lines rather than forcing upgrades. The CVE density in this release cycle — particularly the accounting database SQL injection and the privilege escalation — suggests the accounting storage layer is under active security scrutiny. Feature work in 26.05.x continues on external node support and async step improvements.

◆ Prediction

The accounting database SQL injection (CVE-2026-65139) will likely prompt a broader audit of user-controlled inputs to the accounting storage layer. External hetjob support in 26.05.3 will expand as cloud-burst deployments become more common in AI/HPC workloads.
