Prior to 2.18.0, the frontend GET /artifacts/get route accepts source=http or source=https with caller-controlled bucket and key values, and isAllowedResourceName permits an all-digit decimal host that the URL parser converts to an IPv4 address. The default ALLOWED_ARTIFACT_DOMAIN_REGEX and authorization-disabled standalone configuration allow an unauthenticated caller to fetch internal HTTP resources and receive their response body. In the authenticated multi-user configuration, the same destination-validation defect is reachable by a low-privilege tenant with a valid identity and authorized namespace. Cloud credential disclosure depends on reachable metadata services and attached roles, and the issue does not establish IMDSv2 bypass or credential access when metadata is blocked. This issue is fixed in version 2.18.0.</description></item><item><title>CVE-2026-88984: Kubeflow Pipelines: RBAC bypass on shared pipelines allows any authenticated user to delete or modify global pipelines</title><link>https://vulnfeed.org/cve/CVE-2026-88984/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-88984/</guid><pubDate>Thu, 05 Nov 2026 23:17:01 +0000</pubDate><description>Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.16.1, the multi-user API server treats the empty namespace used by shared or global pipelines as an authorization exception for modification and deletion operations. An authenticated user can modify or delete shared pipeline definitions and versions without the required Kubernetes RBAC permissions, compromising their integrity and availability. Read-only access to shared pipelines remains intentional, single-user deployments intentionally bypass multi-user checks, and execution of a modified pipeline is a conditional downstream consequence. The separate shared-pipeline multipart upload authorization path is outside this advisory and is not remediated by version 2.16.1. This issue is fixed in version 2.16.1.</description></item><item><title>CVE-2026-77596: Kubeflow Pipelines API server lacks authorization for shared pipeline uploads</title><link>https://vulnfeed.org/cve/CVE-2026-77596/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-77596/</guid><pubDate>Thu, 05 Nov 2026 22:23:13 +0000</pubDate><description>Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.18.0, the multi-user HTTP endpoints POST /apis/v2beta1/pipelines/upload and POST /apis/v2beta1/pipelines/upload_version call canUploadVersionedPipeline, which returns without SubjectAccessReview when the target namespace is empty while REQUIRE_NAMESPACE_FOR_PIPELINES defaults to false. A low-privilege tenant can create shared pipelines or inject attacker-controlled versions into existing shared pipelines without the required write permission; if the API server is directly reachable without an authenticating proxy, an unauthenticated caller can exploit the same bypass, while deployments protected by such a proxy do not expose anonymous access. An enabled unpinned recurring run that follows the latest version can then execute the injected specification in another tenant&apos;s namespace under that workload&apos;s service account, while pinned or embedded-specification runs are not automatically substituted. This issue is fixed in version 2.18.0.</description></item><item><title>CVE-2026-88981: Kubeflow Pipelines: Unauthenticated SSRF through artifact provider endpoints</title><link>https://vulnfeed.org/cve/CVE-2026-88981/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-88981/</guid><pubDate>Thu, 05 Nov 2026 22:21:30 +0000</pubDate><description>Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.18.0, the frontend artifact download path for source=s3 or source=minio accepts providerInfo.Params.endpoint, and the archived pod-log path accepts S3-compatible endpoint metadata from workflow status, without requiring those endpoints to match operator-controlled storage configuration. In the shipped authorization-disabled standalone configuration, an unauthenticated caller can make the shared ml-pipeline-ui pod connect to arbitrary reachable hosts and return response data; requests may also reveal an access-key identifier when signed with configured object-store credentials. Multi-user secret-backed metadata remains restricted to the server namespace. This issue is fixed in version 2.18.0.</description></item></channel></rss>
