AWS Ops Wheel CVE-2026-6911

No special conditions required - remote unauthenticated exploitation against default AWS Ops Wheel deployments. The vulnerability is exploitable via standard HTTPS requests to any exposed API Gateway endpoint serving AWS Ops Wheel. Attack complexity is low (CVSS AC:L) because JWT forgery requires only publicly available JWT libraries and knowledge of claim structure. No user interaction (CVSS UI:N) or privileges (CVSS PR:N) are required. Exploitation is not limited by network position, configuration variations, or deployment modes. The only limiting factor is network reachability to the API Gateway endpoint - organizations with API Gateway restricted to VPC-only access or behind additional authentication layers may have reduced exposure, but the vulnerability itself imposes no exploitation barriers once endpoint access is achieved.

This vulnerability represents critical real-world risk despite absence of EPSS or KEV data. The CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) accurately reflects exploitability - remote attackers need zero authentication, no user interaction, and face low attack complexity. SSVC framework assessment: Exploitation is trivial (fully automatable token forgery), technical impact is total (confidentiality, integrity, availability all compromised across tenants), and mission prevalence is situated (AWS Ops Wheel is not universally deployed but used in production AWS environments). The multi-tenant impact escalates risk significantly - a single exploit can compromise data across organizational boundaries. Patch availability from vendor (GitHub PR #164) is confirmed, but requires redeployment rather than automatic update, creating a window of vulnerability until operators take action. The absence of public exploit code may be temporary given the simplicity of JWT forgery attacks. Priority should be IMMEDIATE for organizations running AWS Ops Wheel, as the barrier to exploitation is essentially zero and impact is catastrophic.

An external attacker crafts a JWT token with administrative claims and no valid signature, setting the user role to 'admin' and tenant ID to target any organization in the multi-tenant deployment. They send this forged token in the Authorization header to the AWS Ops Wheel API Gateway endpoint. Because the application fails to verify the JWT signature, it accepts the token as authentic and grants full administrative privileges. The attacker then uses API calls to enumerate all tenant data, exfiltrate sensitive operational configurations, modify infrastructure automation rules to establish persistence, and create new Cognito user accounts for continued access. The entire attack requires only HTTP client capabilities and basic JWT structure knowledge - no authentication credentials, no social engineering, no complex exploit chains.
