Elasticsearch 8.19.19, 9.3.8, 9.4.4 Security Update (ESA-2026-188)
Incorrect Authorization in Elasticsearch Leading to Unauthorized Data Stream Modification Incorrect Authorization (CWE-863) in Elasticsearch can lead to unauthorized data stream modification via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user with sufficient privileges over a single resource could use the Modify Data Streams API to modify a data stream to which they were not otherwise authorized, potentially injecting data into it or affecting its ability to be searched normally. This issue does not allow an attacker to read the contents of a data str…
Kibana 8.19.22, 9.4.7, 9.5.4 Security Update (ESA-2026-187)
Authorization Bypass Through User-Controlled Key in Kibana Leading to Cross-Tenant Data Interception Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana could lead to cross-tenant data interception. In this context, "tenant" refers to a user or team sharing the same Kibana deployment, not a separate Elastic Cloud organization or customer. Kibana's Fleet package installation process allowed a user holding delegated Fleet package-management privileges, without direct Elasticsearch administrative privileges, to claim a data stream identifier already in use by another tenant. Bec…
Elasticsearch 8.19.23, 9.4.8, 9.5.5 Security Update (ESA-2026-185)
Uncontrolled Resource Consumption in Elasticsearch Leading to Denial of Service Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). A low-privileged authenticated user can submit a specially crafted query that causes uncontrolled memory growth in the query processing engine, resulting in an out-of-memory condition that terminates the Elasticsearch node. The condition can be triggered repeatedly, including by queries embedded in shared resources, causing persistent cluster unavailability. Affected Versions: 8.x: All v…
The Shift to cgroup v2 in Kubernetes: What You Need to Know
In Linux, cgroups (control groups) are a kernel feature used for managing system resources. Kubernetes uses cgroups to allocate resources like CPU and memory to containers, ensuring that applications run smoothly without interfering with each other. With the release of Kubernetes v1.31, support for v1 cgroup management moved into maintenance mode . Support for v2 cgroup management has been stable since Kubernetes v1.25. Compared with cgroup v1, cgroup v2 provides a single unified hierarchy, a more consistent interface, and a stronger foundation for resource isolation and modern resource-manag…

Scaling Kubernetes Workloads with Node Swap
Memory is often the first hard limit a Kubernetes cluster hits. Nodes run out of RAM long before they run out of CPU, and the new wave of agentic AI workloads makes this worse. These workloads demand large memory footprints to start up and run untrusted code, then sit idle waiting for the next prompt. That idle but resident memory is expensive, and it caps how many pods a node can hold. This is where swap helps. Kubernetes support for running nodes with swap enabled reached General Availability in v1.34, and by backing that swap with fast NVMe solid state drives (SSDs), a node can page out do…

Demoting i686 Windows targets to std-only
With Rust 1.100.0, the following changes to 32-bit Windows targets will happen: i686-pc-windows-msvc Tier 1 with host tools target will be demoted to Tier 1 without host tools. i686-pc-windows-gnu Tier 2 with host tools target will be demoted to Tier 2 without host tools. Builds of the standard library will continue to be distributed, but host tools such as the compiler will be no longer available. i686-pc-windows-msvc as a Tier 1 target still undergoes CI testing. To build 32-bit Windows binaries, cross-compiling from a still-supported host toolchain (such as a 64-bit Windows ones) will be r…
