CVE-2026-6911
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMissing 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMissing JWT signature verification in AWS Ops Wheel allows attackers to forge JWT tokens with administrative claims. The API Gateway endpoint accepts these crafted tokens without validating the cryptographic signature, enabling unauthenticated access to read, modify, and delete cross-tenant data and manage Cognito User Pool accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify AWS Ops Wheel installationLocate the AWS Ops Wheel application deployment in your environment. Check for the application name in deployed services, containers, or infrastructure-as-code definitions.Affected if The application is named AWS Ops Wheel or is deployed from the aws-ops-wheel repository
-
Verify JWT authentication is in useInspect the application configuration and code to confirm JWT tokens are used for authentication. Look for JWT-related modules, token validation logic, or authentication middleware handling Bearer tokens.Affected if JWT tokens are accepted in the Authorization header for API requests
-
Inspect JWT signature verification implementationReview the JWT validation code or configuration to determine if signature verification is performed. Check for: presence of secret/public key configuration, use of verification libraries (e.g., jwt.verify()), algorithm specification (RS256, HS256), and whether tokens are validated without signature checks.Affected if JWT tokens are accepted without signature verification - tokens pass validation without a valid cryptographic signature or with an explicitly disabled signature check
-
Test token acceptance with forged JWTSend a request to the API Gateway with a self-signed JWT token containing administrative claims (e.g., role: admin, sub: arbitrary-user). Use a tool like curl with an arbitrary payload and invalid signature.Affected if The request succeeds and returns authenticated access without rejecting the invalidly-signed token
-
Check for administrative API accessAttempt to access tenant data endpoints (read/write/delete) or Cognito user pool management API endpoints using an unsigned or incorrectly-signed JWT token.Affected if Administrative operations succeed with a crafted JWT that lacks valid signature verification
Your environment is affected if AWS Ops Wheel is deployed and JWT tokens are accepted without proper cryptographic signature verification, allowing administrative access with arbitrarily crafted tokens.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedRedeploy from the updated repository and audit any forked or derivative code to ensure JWT signature verification is properly implemented.
latest main branch or the version corresponding to PR #164 merge
- Review the changes in PR #164 (https://github.com/aws/aws-ops-wheel/pull/164) to understand the JWT signature verification fix that was implemented
- Pull the latest version of the aws/aws-ops-wheel repository that incorporates the security fix
- Redeploy the AWS Ops Wheel application using the updated codebase
- Verify that JWT signature verification is now properly enforced by testing with invalid signatures
- If using a forked or derivative version of the code, manually apply the fix from PR #164 to ensure signature verification is implemented
