Critical (9.0). EPSS 1.0% chance of exploitation in the next 30 days. Fixed in @aws-amplify/codegen-ui-react 2.20.3.
The AWS Amplify Studio UI component property expressions in the aws-amplify/amplify-codegen-ui package lack input validation. This could potentially allow an authenticated user who has access to create or modify components to run arbitrary JavaScript code during the component rendering and build process.
