Description

Missing JWT signature verification in AWS Ops Wheel allows unauthenticated attackers to forge JWT tokens and gain unintended administrative access to the application, including the ability to read, modify, and delete all application data across tenants and manage Cognito user accounts within the deployment's User Pool, via a crafted JWT sent to the API Gateway endpoint. To remediate this issue, users should redeploy from the updated repository and ensure any forked or derivative code is patched to incorporate the new fixes.
