Amazon Aurora PostgreSQL-Compatible Edition now supports PostgreSQL versions 18.4, 17.10, 16.14, 15.18, and 14.23 which include bug fixes from the PostgreSQL community and Aurora-specific enhancements. We recommend upgrading to the latest minor versions to address known Common Vulnerabilities and Exposures (CVEs) and benefit from these improvements, as detailed in the release notes.  You can upgrade your databases during scheduled maintenance windows using automatic minor version upgrades. To simplify operations at scale, enable automatic minor version upgrades and use the AWS Organizations Upgrade Rollout Policy to orchestrate multiple upgrades in phases, validating on lower-priority environments before upgrading your most critical ones. For more information, see Upgrading Amazon Aurora PostgreSQL DB clusters. Amazon Aurora is designed for high performance and availability at global scale with full PostgreSQL compatibility. It provides scale-to-zero serverless compute, Aurora Global Database for multi-Region resilience, Aurora I/O-Optimized for improved price performance on I/O-intensive workloads, and built-in security and continuous backups. To get started, take a look at our getting started page.

Amazon SageMaker HyperPod now enhances support for Ray with built-in observability, resilient training, accelerated inference and managed development environments. Ray is a popular open-source framework for scaling AI workloads on a unified compute layer, from data processing and distributed training to reinforcement learning and model serving. Running Ray on Kubernetes at production scale can be an operational burden: job hangs, low GPU utilization from static team allocations, and multi-step observability setup. Also, lack of interactive development environment means every code change needs another job submission and familiarity with kubectl. HyperPod now brings easier development, resilient training, and accelerated inference to Ray. Data scientists create, edit, monitor, and delete Ray clusters from a web-based interface in Amazon SageMaker Studio, then attach JupyterLab, Code Editor, or a local IDE to a running Ray cluster and iterate interactively against cluster-scale compute. A multi-node Ray cluster behaves like a local development environment, so you test each change immediately, without waiting for a new job to queue and start. For Observability, HyperPod provisions Grafana dashboards with metrics in Amazon Managed Service for Prometheus and allows one-click access to the Ray Dashboard through a secure browser link, giving you visibility into your workloads from the first run. For training at scale, HyperPod node auto recovery and hung job detection handle GPU faults, job hangs, loss spikes, and degraded throughput. Tiered checkpointing restores state from cluster memory to maximize goodput, and task governance improves compute utilization through quotas, priorities, and preemption. Together, these keep your long training runs progressing through failures and maximize the useful work done per GPU-hour. For inference with Ray Serve, a tiered KV cache reuses cached prefixes to reduce time to first token, and you can deploy Amazon SageMaker JumpStart models directly. Open-source Ray code runs unchanged and you can either adopt the purpose-built experience in SageMaker Studio or take individual capabilities to integrate into your own ML platform. Ray support is available for HyperPod clusters orchestrated by Amazon EKS, in AWS Regions where SageMaker HyperPod is supported. To learn more, see the SageMaker HyperPod documentation, and explore the interactive demo.

Amazon Connect Customer now supports information extraction, which automatically captures key data from voice and chat interactions, reducing manual data capture and improving agent and supervisor productivity. Information extraction captures verbatim values like account numbers, reservation IDs, and product names, as well as derived insights inferred from the conversation such as reason for contact, resolution provided, and next steps promised. You define conversational analytics rules for what to extract and when. Extraction operates on raw contact content before redaction, so you can capture specific data points while still redacting sensitive values from recordings and transcripts. Agents see extracted values during After Contact Work, supervisors use them to search and review contacts, and developers access them programmatically through APIs, Kinesis Data Streams, and S3 output files. You can also feed extracted values directly into rule actions like email notifications, task creation, and case creation, turning unstructured conversations into automated experiences. For example, a travel company can automatically extract 'Hotel Name,' 'Reservation ID,' and 'Reason for call' from interactions, then populate outbound emails and create follow-up tasks, eliminating manual data entry and reducing handle time. To learn more, see Information extraction in the Amazon Connect Customer Administrator Guide, or visit the Amazon Connect Customer website. For a complete list of conversational analytics capabilities available by AWS Region, refer to Availability of Connect Customer features by Region.

The Amazon Elastic Kubernetes Service (Amazon EKS) Capability for Argo CD now supports custom configuration through a standard argocd-cm ConfigMap in your cluster. This capability gives you a fully managed GitOps continuous delivery experience, and you can now tune it to fit how your teams work. You can define custom health checks for your Custom Resources, customize the Argo CD UI banner content, adjust how the capability watches and compares the resources it manages, and more. You configure these settings the same way you do in upstream Argo CD, and AWS applies them to your managed capability. With this launch, cluster administrators now have more control over how Argo CD reports application health. By default, Argo CD has no built-in health logic for Custom Resources, so an Application can report as healthy while its resources are still provisioning, and sync waves can advance before those resources are ready. With a custom health check, you define this logic yourself. For example, a health check for a database resource can hold an Application at progressing until the database is ready. The capability also includes built-in health checks for AWS Controllers for Kubernetes (ACK) and kro (Kube Resource Orchestrator) resources, so these report accurate health with no additional configuration. You can configure the EKS Capability for Argo CD in all AWS Regions where the capability is available. To learn more, see Amazon EKS and Configure Argo CD settings in the Amazon EKS User Guide.

Amazon Simple Email Service (SES) now supports open and click tracking override parameters in the SendEmail and SendBulkEmail APIs. Senders can enable or disable open tracking and click tracking on an individual API call, rather than managing tracking preferences through separate configuration sets. Previously, controlling tracking behavior required maintaining a distinct configuration set for each combination of open- and click-tracking settings. With this new capability, you specify the tracking preference directly in the send request, reducing configuration overhead and simplifying how you honor recipient-level tracking consent. This is useful for senders that must respect per-recipient consent choices to meet data protection requirements such as GDPR and CNIL guidance. The tracking overrides apply per request and take precedence over the tracking behavior defined in the associated configuration set, giving you fine-grained control without changing your existing configuration set structure. There is no additional cost to use this feature. This capability is available in all AWS Regions where Amazon SES is available. To learn more, see the documentation on open and click tracking in the Amazon SES Developer Guide.

Bulletin ID: 2026-055-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/14/2026 13:30 PM PDT Description: The AWS Load Balancer Controller is an open-source Kubernetes controller that manages AWS Elastic Load Balancing resources for Kubernetes clusters. We identified CVE-2026-15738, an incorrect rule precedence ordering issue in the Gateway API listener rule generation logic. When both an HTTPRoute and a GRPCRoute are attached to the same Application Load Balancer (ALB) HTTPS listener with the same hostname, the controller assigns ALB listener rule priorities based on route kind rather than route specificity. This causes all HTTPRoute-derived rules to receive lower ALB priority numbers, evaluated first by the ALB, than GRPCRoute-derived rules, regardless of which route is more specific. A namespace-scoped user with permission to create HTTPRoute objects in a namespace admitted by a shared Gateway can create a catch-all HTTPRoute that intercepts traffic intended for a more-specific GRPCRoute in another namespace.

Bulletin ID: 2026-077-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 08/06/2026 11:00 AM PDT Description: Strands Agents is an open-source SDK for building AI agents. The strands-agents-tools package provides pre-built tools for use with the SDK, including the mongodb_memory, elasticsearch_memory, and mem0_memory tools for storing and retrieving agent memories. We identified CVE-2026-19111, an insecure direct object reference (IDOR) issue in the mongodb_memory, elasticsearch_memory, and mem0_memory tools. Each tool uses a namespace field as the sole tenant-isolation key, and that namespace was exposed as a parameter the large language model (LLM) could control through the tool schema. A crafted prompt could cause a tool to emit a call with a forged namespace, allowing a remote authenticated user to read, modify, or delete memories belonging to other tenants, or to inject false memories into another tenant's namespace. The standalone mongodb_memory and elasticsearch_memory functions additionally exposed connection parameters, which could allow the memory layer to be redirected to an actor-specified cluster.

Bulletin ID: 2026-062-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/21/2026 13:15 PM PDT Description: s2n-tls is an open source C99 implementation of the TLS/SSL protocol. We have identified two distinct issues: - CVE-2026-16317: Silent Drop of TLS 1.3 Encrypted Records in s2n-tls Missing validation of the outer content_type byte on TLS 1.3 encrypted records in s2n-tls allows an active man-in-the-middle to silently drop individual application data records without either endpoint detecting the modification. RFC 8446 Section 5.2 requires that the outer content_type of all encrypted TLS 1.3 records must be application_data (0x17). The s2n-tls AEAD implementation hardcodes this value in the additional authenticated data rather than using the actual wire byte, so the outer content_type is not covered by the authentication tag. All TLS 1.3 connections are affected. Both TLS clients and servers are affected. TLS 1.2 and QUIC connections are not affected. - CVE-2026-16318: QUIC Transport Parameters Memory Leak During HelloRetryRequest in s2n-tls Incorrect use of s2n_alloc instead of s2n_realloc in the QUIC transport parameters extension handler in s2n-tls causes one memory allocation to be leaked each time a QUIC-enabled TLS 1.3 connection goes through a HelloRetryRequest. This can occur during normal handshakes when a client offers a key share group the server does not prefer, and can lead to increased memory consumption on long-running server processes. Only QUIC-enabled deployments are affected. Impacted versions: <= v1.7.5 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.

Bulletin ID: 2026-031-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 05/14/2026 13:00 PM PDT Description: Amazon SageMaker Python SDK is an open-source library for training and deploying machine learning models on Amazon SageMaker. The ModelBuilder component simplifies model deployment by automating model artifact preparation and SageMaker model creation. We identified two issues affecting the model artifact integrity verification mechanism in the ModelBuilder/Serve component: - CVE-2026-8596: We identified a cleartext storage of sensitive information issue in the ModelBuilder/Serve component. When building models using ModelBuilder, the SDK stored an HMAC signing key as a container environment variable (SAGEMAKER_SERVE_SECRET_KEY). This key was returned in plaintext by SageMaker describe APIs (DescribeModel, DescribeEndpointConfig, DescribeModelPackage). A remote authenticated actor with permissions to call these APIs and S3 write access to the model artifact path could extract the key, forge valid integrity signatures for specially crafted model artifacts, and achieve code execution in inference containers. - CVE-2026-8597: We identified a missing integrity verification issue in the Triton inference handler. The Triton handler deserialized model artifacts without performing integrity verification before execution. A remote authenticated actor with S3 write access to the model artifact path could replace model artifacts with a specially crafted pickle payload that would be deserialized without verification, achieving code execution in inference containers. Impacted versions: Amazon SageMaker Python SDK >= v2.199.0 AND <= v2.257.1, >= v3.0.0 AND <= v3.7.1 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
