# CVE-2026-112407

> 8.7 HIGH · 🧪 PoC

## Beschreibung

Incorrect privilege assignment in the IAM policy of AWS CICD-toolchain-for-serverless-applications 1.0.7 through 1.0.10 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.



To remediate this issue, users should upgrade existing toolchain stacks to version 1.0.11 or later.
