CVE-2026-6911 is a critical security vulnerability in AWS Ops Wheel stemming from CWE-347: improper verification of cryptographic signatures. Specifically, the application fails to verify JWT signatures, enabling attackers without authentication to forge tokens and escalate privileges to administrative level. This vulnerability impacts data confidentiality, integrity, and availability by allowing attackers to access and manipulate all tenant data and manage Cognito user accounts. AWS, as the cloud service provider, manages remediation server-side, and users should update any local or forked codebases accordingly. The CVSS v3.1 base score is 9.8, reflecting the critical nature and ease of exploitation over the network without privileges or user interaction.

Successful exploitation allows unauthenticated attackers to forge JWT tokens, resulting in full administrative access to AWS Ops Wheel. Attackers can read, modify, and delete all application data across tenants and manage Cognito user accounts within the User Pool. This compromises data confidentiality, integrity, and availability, and undermines user authentication controls.

AWS manages remediation for this cloud-hosted service, applying fixes server-side. Users should redeploy AWS Ops Wheel from the updated official repository and patch any forked or derivative code to incorporate the fix. Check the AWS security advisory at https://aws.amazon.com/security/security-bulletins/2026-018-aws/ for the latest remediation guidance and confirm that updates have been applied.
