Vulnerability Title
Privilege Escalation via Self-Writable Cognito Custom Attribute in AWS Ops Wheel
Source: NVD (National Vulnerability Database)
Vulnerability Description
Improperly controlled modification of dynamically-determined object attributes in the Cognito User Pool configuration in AWS Ops Wheel before PR #165 allows remote authenticated users to escalate to deployment admin privileges and manage Cognito user accounts via a crafted UpdateUserAttributes API call that sets the custom:deployment_admin attribute. 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.
