CVE-2026-6911: AWS Ops Wheel: Missing JWT Signature Verification
AWS Ops Wheel does not verify the signature of JSON Web Tokens, so an unauthenticated attacker could forge a token and obtain unintended administrative access. The record links this to API Gateway endpoints and notes possible cross-tenant data access and Cognito User Pool account management. The CVSS 3.1 base score is 9.8 (critical), and the sources consulted show no confirmed exploitation.
Overview
CVE-2026-6911 affects AWS Ops Wheel, an application whose API does not verify the signature of JSON Web Tokens (JWT). The weakness is classified as CWE-347, Improper Verification of Cryptographic Signature. The record was published on 2026-04-24 and is currently marked Awaiting Analysis.
Impact
According to the record, an unauthenticated attacker reaching the API Gateway endpoint could submit a crafted token that the application accepts. This could grant unintended administrative access, including reading, modifying and deleting application data across tenants and managing user accounts in the deployment's Cognito User Pool.
Affected products and versions
The product named is AWS Ops Wheel. The structured data lists no affected or fixed version ranges, so the exact vulnerable scope cannot be determined from the sources consulted. The record advises redeploying from the updated repository and patching any forked or derivative code.
Exploitation status
The CVE is not listed in the CISA KEV catalog according to the record, and no confirmed exploitation appears in the sources consulted. The absence of reports does not reduce the urgency given the critical rating and the authentication bypass nature of the flaw.
Remediation and mitigation
- Redeploy AWS Ops Wheel from the updated repository referenced in the vendor pull request and the GitHub security advisory.
- Identify any forks or derivative code and confirm the signature verification fix has been incorporated.
- Where operationally feasible, limit exposure of the API endpoint until the patched deployment is in place.
- Consult the AWS security bulletin for related guidance.
Detection guidance
- Review API Gateway access logs for requests to Ops Wheel endpoints that show unexpected administrative actions or unfamiliar identity claims.
- Audit Cognito User Pool changes, such as account creation, modification or deletion, for activity that administrators cannot explain.
- Check application data for unexpected modifications or deletions, including across tenant boundaries.
Limitations of the available information
The record does not provide affected version ranges, fixed version numbers, or exploitation details. A CVSS 3.1 base score of 9.8 and a CVSS 4.0 score of 9.3 are recorded. The EPSS entry shows a probability of 0.00422 and a percentile of 0.34744, but its date should be verified against the original source. Specific fix details should be confirmed in the linked advisory.
