Description:
CICD-toolchain-for-serverless-applications is an AWS sample application that provisions a CI/CD pipeline for serverless applications through the AWS Serverless Application Repository. We identified CVE-2026-112407, an incorrect privilege assignment in the IAM policy of AWS CICD-toolchain-for-serverless-applications before 1.0.11 that allows remote authenticated users with push access to the application source repository to escalate privileges and access or modify resources outside the application stack in the same AWS account via application templates deployed by the toolchain pipeline.
Impacted versions: =1.0.7 AND <=1.0.10
Resolution:
This issue has been addressed in CICD-toolchain-for-serverless-applications version 1.0.11. We recommend upgrading existing toolchain stacks to version 1.0.11 or later and ensuring any forked or derivative code is patched to incorporate the new fixes.
Workarounds:
There is no workaround available.
