This package is responsible for generating front-end code from UI Builder entities. The vulnerability resides in the expression-binding function, which fails to adequately validate component schema properties before processing them.\u003c/p\u003e\n\u003cp\u003eAn authenticated attacker who can manipulate component schemas via the AWS Amplify Studio interface or the \u003ccode\u003ecreate-component\u003c/code\u003e CLI command can inject arbitrary JavaScript expressions. These expressions are executed during the component rendering and build phases. Because these processes often run in the context of the user's build environment or automated CI/CD pipelines, this flaw could lead to unauthorized code execution, potential exfiltration of environment secrets, or further compromise of the development infrastructure. Users are advised to upgrade to version 2.20.4 or later to remediate this issue.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation allows for arbitrary code execution within the build environment of applications utilizing AWS Amplify Studio.
