CyberRota Analysis
AI-GeneratedKubernetes users running versions prior to 2.17.0 are vulnerable to a critical server-side request forgery (SSRF) flaw in the Kubeflow Pipelines frontend, which allows attackers to send unauthorized requests to internal services by manipulating the /_proxy/ route. This vulnerability can expose sensitive information, such as cloud metadata credentials and internal Kubernetes APIs, potentially leading to unauthorized access or modification of cluster resources. Organizations utilizing Kubeflow for machine learning workflows should prioritize upgrading to version 2.17.0 to mitigate this risk.

Original NVD Description
Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.17.0, the Kubeflow Pipelines frontend exposes an unauthenticated server-side request forgery vulnerability through the /_proxy/ route in frontend/server/proxy-middleware.ts. The _routePathWithReferer() function accepts an arbitrary attacker-controlled HTTP or HTTPS target and passes its origin to createProxyMiddleware without a host allowlist or filtering for loopback, link-local, RFC1918, or cluster-local addresses. The route remains outside the authorization middleware when ENABLE_AUTHZ=true and is reachable through /apis/v1beta1/_proxy/, /apis/v2beta1/_proxy/, /pipeline/apis/v1beta1/_proxy/, and /pipeline/apis/v2beta1/_proxy/, including through a crafted Referer header. Requests can forward attacker-controlled methods, headers such as Authorization, Cookie, and X-Forwarded-For, and POST bodies to reachable internal services, while returning the upstream response to the unauthenticated client. This can expose cloud metadata credentials, Kubernetes or service APIs, and other cluster-internal endpoints to unauthorized read or modification. This issue is fixed in version 2.17.0.
