Aug 19, 2026A flaw was found in the `cluster-proxy-addon` component of Multicluster Engine for Kubernetes.CVE-2026-66794 · Other software · Red Hat · reported by Red HatCritical 9.3
A flaw was found in the `cluster-proxy-addon` component of Multicluster Engine for Kubernetes. This vulnerability allows an unauthenticated attacker, who can access the user-facing route, to bypass authentication and authorization checks. By manipulating URL path segments, the attacker can proxy requests to arbitrary services across any managed cluster. This enables unauthorized access to internal services that would otherwise be protected, potentially leading to information disclosure or further compromise of the cluster environment.

A flaw was found in volsync-addon-controller. This vulnerability allows an attacker to inject malicious YAML (Yet Another Markup Language) code into the OpenShift Lifecycle Manager (OLM) Subscription resource. This is due to improper escaping of annotation values when they are rendered into YAML. Successful exploitation could lead to unauthorized modification or control over OLM Subscription configurations, potentially impacting software management within the cluster. This issue primarily affects systems where the 'volsync-addon-deploy-type: olm' annotation is explicitly enabled.

A flaw was found in the search-v2-operator. This vulnerability allows a privileged user, specifically a Custom Resource (CR) editor, to manipulate Search CR fields such as imageOverride, arguments, and environment variables without proper validation. By exploiting this, an attacker can mount arbitrary secrets into a search container's environment or replace the container image with an attacker-controlled one. This leads to privilege escalation and can result in a full cluster compromise due to the ServiceAccount's extensive impersonation permissions.

Aug 19, 2026Contour is a Kubernetes ingress controller using Envoy proxy.CVE-2026-50149 · Other software · projectcontour · reported by GitHubMedium 6.5
Contour is a Kubernetes ingress controller using Envoy proxy. In versions 1.23.0 through 1.33.4, when an `HTTPProxy` is configured with incompatible combination of both `.spec.virtualhost.tls.enableFallbackCertificate: true` and `.spec.virtualhost.jwtProviders`, Contour does not reject the configuration. Consequently, requests from clients that do not send TLS SNI or send an unrecognized SNI (one that does not match any `HTTPProxy` FQDN) bypass configured JWT verification and are proxied to upstream services without a valid token. This issue is fixed in Contour v1.33.5. Contour now rejects and marks invalid any `HTTPProxy` resources that combine `.spec.virtualhost.tls.enableFallbackCertificate: true` with `.spec.virtualhost.jwtProviders`. Affected resources will receive a status condition with the error reason `TLSIncompatibleFeatures`. As a workaround, do not enable `.spec.virtualhost.tls.enableFallbackCertificate` on `HTTPProxy` resources that also define `.spec.virtualhost.jwtProviders`. Remove one of the two settings to avoid the invalid configuration.

Aug 13, 2026Cleartext Storage of Sensitive Information in an Environment Variable (CWE-526) in Elastic Cloud on Kubernetes (ECK) can lead to information disclosure via RetrCVE-2026-72648 · Other software · Elastic · reported by security@elastic.coMedium 6.5
Cleartext Storage of Sensitive Information in an Environment Variable (CWE-526) in Elastic Cloud on Kubernetes (ECK) can lead to information disclosure via Retrieve Embedded Sensitive Data (CAPEC-37). When ECK reconciles a Fleet Server resource that authenticates to Elasticsearch with a service account token, the token is written into the generated workload specification in cleartext rather than being referenced from the Kubernetes Secret that ECK maintains for the other credentials on the same path. Any principal able to read workload specifications in the affected namespace can therefore read a live Elasticsearch credential, even when Kubernetes RBAC does not grant that principal access to Secrets.

Aug 11, 2026A flaw was found in insights-client.CVE-2026-71845 · Other software · Red Hat · reported by Red HatMedium 6.3
A flaw was found in insights-client. The setDefault() function logs the value of every environment variable it processes, including CCX_TOKEN, a bearer credential used in disconnected cluster deployments. When glog verbosity is set to level 2 or higher, the token is written in clear text to the pod log on every startup. An attacker with access to pod logs or centralized logging could obtain the credential, leading to unauthorized access to the CCX API.

Aug 11, 2026A flaw was found in insights-client.CVE-2026-71475 · Other software · Red Hat · reported by Red HatMedium 6.8
A flaw was found in insights-client. A compromised managed cluster, referred to as a 'spoke', can inject unencoded data into the Insights API URL path. This occurs because the ClusterID, which is controlled by the spoke, is used directly in the request path without proper validation or URL encoding. This vulnerability allows a malicious spoke to redirect authenticated requests to unintended API endpoints, potentially leading to information disclosure or unauthorized access.

A flaw was found in insights-client. When the application receives a non-200 response, it logs the request headers, which can include the cloud.openshift.com pull-secret token. A local user with access to pod logs on the hub could read this long-lived credential. This information disclosure could grant unauthorized access to Red Hat cloud services.

A flaw was found in acm-search-v2-api-rhel9. When the `getFederationConfig` function refreshes its cache, it improperly reuses a user's bearer token for all subsequent federated requests until the cache expires. This allows other authenticated users to gain unauthorized access to remote managed hub search results, leading to information disclosure.

A flaw was found in search-v2-api. The authentication middleware in the affected component unconditionally skips authentication when a request includes an `Upgrade: websocket` header. An unauthenticated attacker can exploit this by sending a specially crafted HTTP POST request to the `/federated` endpoint with the `Upgrade: websocket` header. This allows the attacker to bypass authentication and access federated search results across all configured remote managed hubs, leading to information disclosure.

Protection mechanism failure for some Cluster Management Toolkit for Kubernetes software before version v0.8.5 within Ring 3: User Applications may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Aug 5, 2026A flaw was found in the Application Subscription controller (multicluster-operators-subscription) of Red Hat Advanced Cluster Management for Kubernetes (ACM).CVE-2026-10090 · Other software · Red Hat · reported by Red HatCritical 9
A flaw was found in the Application Subscription controller (multicluster-operators-subscription) of Red Hat Advanced Cluster Management for Kubernetes (ACM). A user with namespace-scoped "edit" privileges in an ACM hub namespace can create a Channel resource pointing to a Helm repository they control and a Subscription resource referencing it. The app-subscription controller fetches and applies the Helm chart contents with its own elevated authority, without verifying whether the subscription creator holds the "open-cluster-management:subscription-admin" role and without restricting applied resources to the subscription namespace. This allows the attacker to include cluster-scoped resources in the Helm chart, such as a ClusterRoleBinding granting the attacker's ServiceAccount the "cluster-admin" ClusterRole. Successful exploitation results in full cluster-admin privilege escalation. This contradicts the ACM documentation which states that non-subscription-admin users should have resources deployed into the subscription namespace only.

A flaw was found in the Multicluster Engine for Kubernetes ClusterCurator controller. A tenant administrator with namespace-scoped privileges can exploit this vulnerability by creating a namespaced ClusterCurator. This action inadvertently grants the tenant administrator the ability to mint a token for a ServiceAccount with cluster-wide administrative authority. This leads to a privilege escalation, allowing the tenant administrator to gain full control over the cluster.

Aug 1, 2026Traefik versions >= v3.7.0 and <= v3.7.7 contain a path traversal vulnerability in the Kubernetes Ingress NGINX provider's RewriteTarget middleware (generated fCVE-2026-67309 · Other software · traefik · reported by VulnCheckHigh 7.8
Traefik versions >= v3.7.0 and <= v3.7.7 contain a path traversal vulnerability in the Kubernetes Ingress NGINX provider's RewriteTarget middleware (generated from the nginx.ingress.kubernetes.io/rewrite-target annotation). When an Ingress path uses a regex that captures attacker-controlled text without requiring a path separator (e.g., path /api(.*) with rewrite target /$1), a crafted request such as /api../admin matches the public router, is rewritten to a dot-segment traversal path (/../admin), and is forwarded without post-replacement normalization validation. A backend that normalizes dot segments resolves the path to a protected endpoint (e.g., /admin) reachable only through a separate router secured with BasicAuth, DigestAuth, or ForwardAuth, resulting in route-level authentication bypass. The issue is fixed in v3.7.8.

A flaw was found in Red Hat Advanced Cluster Security for Kubernetes (RHACS). When processing Kubernetes Deployments, ACS replaces deployment identity metadata based on the openshift.io/encoded-deployment-config label. A user with permission to create Deployments can set this label to "null", causing ACS to treat the workload as having empty UID, name and labels and namespace "default". This bypasses deploy-time policy detection and enforcement visibility, prevents correct persistence in Central and breaks violation reporting and compliance correlation for the affected deployment.
