## Summary The AWS Cloud Development Kit (AWS CDK) is an open-source software development framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. We identified an issue in which explicitly setting `encrypted: true` on the `S3LoggingOptions` property of an AWS CodeBuild project construct produces the opposite of the intended behavior, disabling encryption on CodeBuild build logs stored in S3. ## Impact The `S3LoggingOptions.encrypted` property in the `aws-codebuild` module uses positive polarity (`true` = encryption ON), but is mapped directly to t

### Summary AWS CDK (aws-cdk-lib) is an open-source framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. OS command injection issue in the NodejsFunction Docker bundling pipeline in aws-cdk-lib before 2.260.0 that might allow an actor who controls dependency version strings in a project's package.json file to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters in the OsCommand helper. This issue requires the actor to control the content of a package.json dependency version string that is processed dur

### Summary AWS CDK (`aws-cdk-lib`) is an open-source framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. OS command injection in the `NodejsFunction` local bundling pipeline in `aws-cdk-lib` before 2.245.0 (2.246.0 on Windows) might allow a threat actor who controls the value of one or more bundling properties (`externalModules`, `define`, `loader`, `inject`, or `esbuildArgs`) to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters. This issue requires the threat actor to control the value of one or

### Summary The [AWS Cloud Development Kit (AWS CDK)](https://aws.amazon.com/cdk/) is an open-source software development framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. In the CDK, developers organize their applications into reusable components called "[constructs](https://docs.aws.amazon.com/cdk/v2/guide/constructs.html)," which are organized into a hierarchical tree structure. One of the features of this framework is the ability to call "[Aspects](https://docs.aws.amazon.com/cdk/v2/guide/aspects.html)," which are mechanisms to set configu

### Summary The [AWS Cloud Development Kit (CDK)](https://aws.amazon.com/cdk/) is an open-source framework for defining cloud infrastructure using code. Customers use it to create their own applications which are converted to AWS CloudFormation templates during deployment to a customer’s AWS account. CDK contains pre-built components called "[constructs](https://docs.aws.amazon.com/cdk/v2/guide/constructs.html)" that are higher-level abstractions providing defaults and best practices. This approach enables developers to use familiar programming languages to define complex cloud infrastructure

### Summary The [AWS Cloud Development Kit (CDK)](https://aws.amazon.com/cdk/) is an open-source framework for defining cloud infrastructure using code. Users use it to create their own applications, which are converted to AWS CloudFormation templates during deployment to a user's AWS account. AWS CDK contains pre-built components called "constructs," which are higher-level abstractions providing defaults and best practices. This approach enables developers to use familiar programming languages to define complex cloud infrastructure more efficiently than writing raw CloudFormation templates.

### Impact Users who use IAM OIDC custom resource provider package will download CA Thumbprints as part of the custom resource workflow, https://github.com/aws/aws-cdk/blob/d16482fc8a4a3e1f62751f481b770c09034df7d2/packages/%40aws-cdk/custom-resource-handlers/lib/aws-iam/oidc-handler/external.ts#L34. However, the current `tls.connect` method will always set `rejectUnauthorized: false` which is a potential security concern. CDK should follow the best practice and set `rejectUnauthorized: true`. However, this could be a breaking change for existing CDK applications and we should fix this with a

CVE: CVE-2025-23206

If you are using the `eks.Cluster` or `eks.FargateCluster` construct we need you to take action. Other users are not affected and can stop reading. ### Impact The AWS Cloud Development Kit (CDK) allows for the definition of Amazon Elastic Container Service for Kubernetes (EKS) clusters. `eks.Cluster` and `eks.FargateCluster` constructs create two roles that have an overly permissive trust policy. The first, referred to as the _CreationRole_, is used by lambda handlers to create the cluster and deploy Kubernetes resources (e.g `KubernetesManifest`, `HelmChart`, ...) onto it. Users with CD
