Vulnerability from fkie_nvd - Published: 2026-02-12 22:16 - Updated: 2026-02-13 14:23
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
Summary
Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer. In 0.19.0 and earlier, a vulnerability exists in the Air Traffic Controller (ATC) component of Yoke. The ATC webhook endpoints lack proper authentication mechanisms, allowing any pod within the cluster network to directly send AdmissionReview requests to the webhook, bypassing Kubernetes API Server authentication. This enables attackers to trigger WASM module execution in the ATC controller context without proper authorization.

En la versi\u00f3n 0.19.0 y anteriores, existe una vulnerabilidad en el componente Air Traffic Controller (ATC) de Yoke. Los puntos finales del webhook de ATC carecen de mecanismos de autenticaci\u00f3n adecuados, lo que permite que cualquier pod dentro de la red del cl\u00faster env\u00ede directamente solicitudes de AdmissionReview al webhook, eludiendo la autenticaci\u00f3n del Kubernetes API Server. Esto permite a los atacantes activar la ejecuci\u00f3n de m\u00f3dulos WASM en el contexto del controlador ATC sin la autorizaci\u00f3n adecuada."
