CVE-2026-108096
Description
A flaw was found in graphql-index-transformer in AWS Amplify. Due to improper authorization controls in generated query resolvers, an authenticated remote attacker can submit crafted queries to access data belonging to other users. This issue results in unauthorized information disclosure across accounts within the same application.
Statement
This vulnerability is rated as Moderate impact because exploitation requires existing authenticated access and is constrained to reading data exposed via specific index resolvers within the application backend. Red Hat does not package or distribute the AWS Amplify API category or its index transformer constructs in any supported products. Therefore, standard Red Hat enterprise environments and deployments are not directly exposed.
