CVE-2026-11417: CWE-78: Improper Neutralization of Special Elements used in an OS Command in AWS AWS Cloud Development Kit library
OS command injection in the NodejsFunction local bundling pipeline in aws-cdk-lib before 2.245.0 (2.246.0 on Windows) might allow an 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 more of the affected bundling properties in the CDK application. To remediate this issue, users should upgrade to aws-cdk-lib 2.245.0 (2.246.0 on Windows) or later.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-11417) involves improper neutralization of special elements used in OS commands (CWE-78) within the NodejsFunction local bundling pipeline of aws-cdk-lib versions prior to 2.245.0 (2.246.0 on Windows). An attacker controlling values of bundling properties such as externalModules, define, loader, inject, or esbuildArgs can inject shell metacharacters, leading to arbitrary command execution on the host running the AWS CDK toolchain. The issue requires the attacker to have control over these bundling properties in the CDK application. AWS has released fixed versions 2.245.0 (2.246.0 on Windows) to remediate this vulnerability.
Potential Impact
Successful exploitation allows an attacker with limited privileges (local access with the ability to influence bundling properties) to execute arbitrary OS commands on the host running the AWS CDK toolchain. This can lead to full compromise of the host environment, including confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
A patch is available. Users should upgrade aws-cdk-lib to version 2.245.0 or later (2.246.0 or later on Windows) to remediate this vulnerability. Since this is a library used in local development environments, applying the upgrade promptly is recommended to prevent exploitation. The vendor advisory at https://aws.amazon.com/security/security-bulletins/2026-041-aws/ should be consulted for official guidance.
