CVE-2024-45037Network attack vector

Authenticated API access via omitted authorization scopes

Published Aug 27, 2024 · Updated Aug 27, 2024

Incorrect authorization in AWS CDK 2.142.0 through 2.148.0 allows remote authenticated users to read or modify protected API data. In aws-apigateway Method synthesis, authorizationScopes is emitted only when authorizationTypeOptions resolves to Cognito, but that optional value can be unset even when CognitoUserPoolAuthorizer supplies the effective type. Exposure requires a RestApi using CognitoUserPoolAuthorizer with scopes and deployment from an affected release; valid Cognito access then reaches methods outside the token's scopes.
