Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.94%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The AWS Amplify Studio UI component property expressions in the aws-amplify/amplify-codegen-ui package lack input validation.
