CVE-2026-6912

Privilege Escalation via Self-Writable Cognito Custom Attribute in AWS Ops Wheel

State: Published
Severity: 8.7 High
Published: Apr 24, 2026
Updated: Apr 24, 2026
Reserved: Apr 23, 2026

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.
