CVE-2026-18941

Feast: feast-operator: feast: default authentication mode is no_auth — shared multi-tenant instances deployed without authentication

A flaw was found in Feast and feast-operator. The default configuration for both the Feast SDK and the feast-operator is "no_auth," meaning no security manager is installed. This default allows unauthenticated and unauthorized access to feature-server, registry-server, and offline-server endpoints. A remote attacker, by exploiting this missing authentication, could achieve remote code execution (RCE) by storing a malicious User-Defined Function (UDF) on the feature-server, trigger a denial of service (DoS) by forcing re-materialization of all tenant features, and gain unauthorized access to cross-tenant data.

Data-sciences-pipeline: dsp: v1 argo template path accepts arbitrary workflow spec, bypassing all v2 security hardening

A flaw was found in Data Science Pipelines (DSP). An attacker with namespace editor privileges can bypass security hardening by submitting a malicious Argo Workflow through the V1 API path. This allows the API server to create pods with elevated privileges, acting as a 'confused deputy' on behalf of the attacker. Successful exploitation grants the attacker node-root access, enabling arbitrary code execution and full control over the underlying node.

Quay: quay: webhook notification ssrf -- hostname-string blocklist trivially bypassable

A flaw was found in Quay. An authenticated repository administrator could bypass the hostname blacklist in webhook notifications, leading to a Server-Side Request Forgery (SSRF) vulnerability. This allows the Quay application to be tricked into sending requests to internal network resources, such as cloud metadata services or other services within the cluster. Consequently, this could lead to the disclosure of sensitive information from these internal services.

Quay: repository auto-prune policy uuid idor in quay api

A flaw was found in Quay. An authenticated attacker can access repository auto-prune configurations from other namespaces, leading to unauthorized information disclosure. This issue occurs because the application does not properly enforce namespace scoping when retrieving policy details by repository name and policy identifier. To exploit the vulnerability, the attacker must manage a repository sharing the target's name and know the target policy's unique identifier.

Project-koku/koku-metrics-operator: koku-metrics-operator: service-account client credentials sent to user-controlled token_url

A flaw was found in koku-metrics-operator. The operator's CostManagementMetricsConfig custom resource allows a user able to edit the CR to specify an arbitrary OAuth token endpoint. When authentication.type is set to service-account, the operator sends the tenant's Red Hat SSO client_id and client_secret to this user-controlled URL, allowing the attacker to obtain the credentials.

Rubygem-smart_proxy_dynflow: task update and done callbacks accept unauthenticated requests

Missing authentication has been found in remote-execution task updates in the smart_proxy_dynflow package. The progress and completion callbacks accept a report when the one-time token is missing. A network attacker or user must already know the identifier of a running job. This applies when remote execution is set to pull or pull-mqtt mode. They can send their own job output and mark the job as a success or a failure. The job is then recorded with that result.

Quay: quay: dom-based cross-site scripting via oauth local callback format=json parameter

A flaw was found in Quay. A cross-site scripting (XSS) vulnerability in the OAuth callback handler allows a remote attacker to execute arbitrary JavaScript code within a user's browser session. By tricking a logged-in user into visiting a specially crafted link, an attacker can exploit improper input sanitization to run client-side scripts in the application context. Successful exploitation could allow the attacker to compromise the user's session, access sensitive registry information, or perform unauthorized actions on their behalf.

Quay: quay: dom-based cross-site scripting via unvalidated redirect_url on signin page

A flaw was found in Quay. A remote attacker could trick a user into logging in through a crafted link, resulting in cross-site scripting (XSS). Because the application does not validate the redirect destination before navigating, this flaw allows the execution of arbitrary script in the context of the victim's authenticated browser session. Successful exploitation requires the target Quay deployment to use direct database authentication and the victim to complete login through the malicious URL.

Odh-dashboard: odh-dashboard: backend port 8080 trusts x-forwarded-access-token without origin validation

A flaw was found in odh-dashboard, the web console component of Red Hat OpenShift AI (RHOAI). Due to incorrect network binding, a malicious actor within the cluster can bypass authentication and impersonate any user by providing an arbitrary access token. This allows an attacker to gain unauthorized access to the Kubernetes API, potentially leading to arbitrary code execution, privilege escalation, or information disclosure.

A flaw was found in the `guardrails-detectors` component. This vulnerability allows a remote attacker to perform a blind Server-Side Request Forgery (SSRF) by submitting a specially crafted XML Schema Definition (XSD) string. This can lead to unauthorized access to sensitive information, including credentials from cloud metadata services, Kubernetes API, internal MinIO, and other internal network endpoints. Additionally, it enables local file reads of critical data such as service account tokens and pod secrets.

Odh-dashboard: odh-dashboard: confused-deputy privilege escalation via unchecked roleref in rolebinding creation

A flaw was found in odh-dashboard. An authenticated user of the dashboard can exploit a vulnerability related to how RoleBindings are created. The system does not properly validate the `roleRef` field, allowing a user to specify an arbitrary role, including highly privileged ones like `cluster-admin`. This can lead to privilege escalation, where an attacker gains unauthorized elevated access within their namespace and potentially persistent control over the system.

Data-science-pipelines-operator: dspo: cryptographically weak secret generation (math/rand) for db and s3 credentials

A flaw was found in the Data Science Pipelines Operator. This vulnerability allows an unauthenticated attacker to derive sensitive credentials, such as MariaDB root/user passwords and MinIO access/secret keys, if they can access the MinIO Route or MariaDB Service. The flaw occurs because the operator uses a cryptographically weak pseudo-random number generator (PRNG) to generate these credentials, making them predictable. Successful exploitation could lead to unauthorized access to all pipeline artifacts and metadata, resulting in significant information disclosure.

Odh-training-operator-rhel9: rhoai fork aggregates training job create onto native edit/admin clusterroles

A flaw was found in the RHOAI training-operator. This vulnerability allows a user with standard edit or admin roles in any Kubernetes namespace to escalate their privileges. Through the creation of training jobs, an attacker can impersonate service accounts, access the host filesystem, and potentially execute arbitrary code remotely. This issue arises from the aggregation of training job permissions onto native Kubernetes edit and admin ClusterRoles, coupled with unrestricted PodTemplateSpec passthrough.
