CVE-2026-6912Network attack vector

Privilege escalation via self-writable Cognito attribute

Published Apr 24, 2026 · Updated Apr 24, 2026

Privilege escalation in AWS Ops Wheel v2 PR #147 through PR #163 allows remote authenticated users to gain deployment admin access. The Cognito User Pool Client permits UpdateUserAttributes requests to write custom:deployment_admin because it does not restrict self-writable attributes. Any authenticated application account can then read, modify, or delete cross-tenant application data and manage Cognito users.
