aws-cdk-lib: OS Command Injection in NodejsFunction Docker Bundling

CVE-2026-13760 / GHSA-vcrf-j523-4mrf

More information

Details

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 during Docker-based bundling with nodeModules specified.

Impact

During Docker-based Lambda bundling, when the nodeModules option is specified, NodejsFunction assembled a shell command string, including file-operation commands generated by an internal OsCommand helper, from the version strings of the modules listed in nodeModules, and executed it via a shell (bash -c) inside the bundling container. These version strings were interpolated without shell escaping, so values containing shell metacharacters could execute arbitrary commands inside the bundling container - which has read/write bind mounts to the host filesystem - with the privileges of the user running cdk synth, cdk deploy, or cdk diff. Leveraging this issue requires an actor to control a dependency version string for one of the listed modules - for example via an untrusted npm package referenced through nodeModules.

Impacted versions:

< 2.260.0

Patches

This issue has been addressed in aws-cdk-lib version 2.260.0 (PR #​38133). We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Workarounds

Ensure that the modules listed in the nodeModules bundling option - and the version strings declared for them in your project's package.json, as well as the versions of the corresponding installed packages - come only from trusted sources, and audit third-party constructs and dependencies that introduce them. Using local bundling instead of Docker-based bundling avoids the affected code path. Upgrading to a fixed version is the recommended remediation.

AWS CDK CodeBuild S3 Log Encryption Boolean Inversion

GHSA-464c-974j-9xm6

More information

Details

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 the CloudFormation S3LogsConfig.EncryptionDisabled field, which uses negative polarity (true = encryption OFF). Because the value is not negated before being passed to CloudFormation, any explicit assignment produces inverted behavior:

• Setting encrypted: true (intending encryption ON) causes CloudFormation to receive EncryptionDisabled: true, disabling encryption.

• Setting encrypted: false (intending encryption OFF) causes CloudFormation to receive EncryptionDisabled: false, enabling encryption.

Users who omit the property entirely are not affected, as undefined passes through to CloudFormation, which defaults to encryption enabled.

Users affected by this issue could have CodeBuild S3 build logs stored using SSE-S3 (Amazon S3-managed keys, AES-256) rather than the AWS managed keys that CodeBuild applies by default. Since January 5, 2023, Amazon S3 automatically encrypts all new object uploads with SSE-S3, so logs written after that date remain encrypted at rest. However, logs written prior to that date to buckets that did not have default encryption configured at the time are potentially not encrypted at rest.

Impacted versions: >= 1.75.0 and <= 2.252.0

Patches

This issue has been addressed in aws-cdk-lib version 2.253.0. Upgrade to the latest version and ensure any forked or derivative code is patched to incorporate the new fixes.

Workarounds

Users who are unable to immediately upgrade to version 2.253.0 should omit the encrypted property from their S3LoggingOptions configuration entirely. When the property is omitted, the value is not passed to CloudFormation, and CodeBuild applies its default behavior of encrypting build logs using AWS managed keys.

⚠ BREAKING CHANGES

• lambda: Runtime.NODEJS_LATEST now resolves to nodejs24.x in every region. Customers who pin to a concrete runtime (Runtime.NODEJS_22_X, useLatestRuntimeVersion: false in aws-lambda-nodejs.NodejsFunction) are unaffected. Existing AWS::Lambda::Function resources synthesized with NODEJS_LATEST will see Runtime: nodejs22.x → Runtime: nodejs24.x on next deploy. Lambda accepts runtime updates in place.

  Customer-code compatibility — IMPORTANT: Node.js 24 removes support for callback-style asynchronous handlers ((event, context, callback) => {...}) per the launch blog. Customers whose Lambda code still uses callback-based handlers will see runtime errors after the bump. Customers should migrate to async (event, context) => {...} or pin to Runtime.NODEJS_22_X explicitly.
