CVE-2026-70496 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 9.9 Critical
A flaw was found in search-v2-operator. The operator's ClusterRole has permissions equivalent to a cluster administrator, allowing it to impersonate other entities, write Role-Based Access Control (RBAC) configurations, approve Certificate Signing Requests (CSRs), and manage ManifestWork. This grants excessive privileges beyond what is necessary for the operator's intended function, potentially leading to privilege escalation within the cluster.
CVE-2026-70495 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 8.8 High
A flaw was found in search-v2-operator. This component's `search-serviceaccount` has overly broad permissions, allowing it to impersonate users and groups across the entire cluster. If an attacker gains access to any of the pods running under this service account, they could exploit this to achieve `system:masters` access, granting them full control over the cluster.
CVE-2026-70398 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 9.6 Critical
A flaw was found in multicloud-integrations, a component of Red Hat Advanced Cluster Management (RHACM). This vulnerability allows an authenticated user, referred to as a tenant, to manipulate the GitOpsCluster controller. By exploiting this, a tenant can redirect sensitive spoke cluster bearer tokens from secure locations to a namespace they control. This unauthorized access to tokens can lead to the disclosure of critical information and bypass security policies within ArgoCD AppProjects.
CVE-2026-67567 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 9.9 Critical
A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a tenant, who has the ability to create HelmRelease custom resources (CRs), to bypass existing security controls. The system's HelmRelease controller processes Helm chart templates using its own elevated ServiceAccount privileges without proper validation. This enables the tenant to deploy arbitrary resources across the entire cluster, leading to a significant security compromise.
CVE-2026-66878 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 7.7 High
A flaw was found in multicloud-operators-subscription. A privileged user, specifically a namespace administrator capable of creating Channel and Subscription resources, can exploit this vulnerability. By manipulating the Channel.Spec.SecretRef.Namespace field, the user can cause the system to copy sensitive Secret contents from other namespaces into their own, leading to information disclosure.
CVE-2026-66793 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 8.8 High
A flaw was found in the governance-policy-addon-controller component of Red Hat Advanced Cluster Management for Kubernetes. A user with permissions to annotate the namespaced ManagedClusterAddOn resource can override the governance-policy container image. This allows an attacker to run a controlled image with cluster-admin privileges on the managed cluster, leading to arbitrary code execution and privilege escalation.
CVE-2026-66792 1 Redhat 6 Acm, Advanced Cluster Management For Kubernetes, Multicluster Globalhub and 3 more 2026-08-27 9.9 Critical
A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a user on a managed cluster to escalate their privileges by creating a Subscription with specific, crafted annotations. Successful exploitation grants the attacker the ability to deploy resources into any namespace with the elevated permissions of the controller's Service Account, potentially leading to unauthorized access and control over cluster resources.
CVE-2026-66781 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 6.5 Medium
A flaw was found in the Submariner operator. The Submariner Custom Resource (CR), used for configuring network connectivity, stores the IPsec pre-shared key (PSK) in an unencrypted format. This key, which is critical for securing communication between Kubernetes clusters, can be accessed by unauthorized parties. Such access enables an attacker to passively decrypt network traffic flowing between any two clusters in the mesh, resulting in sensitive information disclosure.
CVE-2026-66780 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 9.9 Critical
A flaw was found in the submariner-operator component. The `submariner-k8s-broker-cluster` Role, which is assigned to joined clusters, possesses excessive permissions. This allows a compromised cluster to alter network configurations, specifically by overwriting other clusters' endpoint information. Consequently, an attacker can redirect inter-cluster tunnel traffic, enabling a Man-in-the-Middle (MITM) attack across the entire cluster mesh.
CVE-2026-76139 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-27 8 High
A flaw was found in acm-operator-bundle. The build process for this component downloads and runs a script from a remote source without verifying its authenticity or integrity. This script gains access to sensitive credentials, such as GitHub access tokens and registry passwords, used in the build environment. A remote attacker could exploit this vulnerability to inject malicious code, leading to unauthorized access to build resources and potential compromise of the resulting operator bundle.
CVE-2026-71467 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-26 7.5 High
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.
CVE-2026-16242 1 Redhat 10 Acm, Advanced Cluster Management For Kubernetes, Logging and 7 more 2026-08-26 9.4 Critical
A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert (and without token-based agent authentication), so client certificates were not validated. A remote attacker who can reach the Konnectivity cluster endpoint could connect as an unauthenticated agent, join the routing pool, and potentially proxy, inspect, modify, or drop control-plane-to-node traffic.
CVE-2026-66785 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-25 9.9 Critical
A flaw was found in Submariner. This vulnerability allows a malicious cluster (spoke) to redirect network traffic from other connected clusters (peer clusters) by publishing a specially crafted network endpoint. The system fails to properly validate the network subnets provided by the malicious cluster, enabling it to declare arbitrary network ranges. Consequently, all network traffic intended for these arbitrary ranges from peer clusters will be rerouted through the attacker's tunnel, potentially leading to unauthorized information disclosure or network disruption.
CVE-2026-75924 1 Redhat 3 Acm, Advanced Cluster Management For Kubernetes, Multicluster Engine 2026-08-21 8.7 High
A flaw was found in managed-serviceaccount. A compromised addon-manager pod, due to its ClusterRole granting excessive permissions, can read any secret across all namespaces. Additionally, it can approve arbitrary Certificate Signing Requests (CSRs), which could lead to information disclosure and privilege escalation within the cluster.
CVE-2026-66782 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 7.8 High
A flaw was found in the Submariner operator. This vulnerability allows for the exposure of a long-lived broker service account (SA) bearer token within the Submariner Custom Resource (CR) specification. An attacker with access to the cluster's etcd database or through `kubectl get` commands could obtain this token. The possession of this token grants full control over the mesh network, enabling unauthorized management of network resources such as endpoints and secrets.
CVE-2026-66783 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 8.2 High
A flaw was found in the `submariner-operator` component of Red Hat Advanced Cluster Management for Kubernetes. This vulnerability allows a cluster administrator, or any user with permissions to modify the Submariner Custom Resource (CR), to specify an unvalidated image path. This lack of validation enables an attacker to execute arbitrary code with elevated privileges across the entire cluster, including control-plane nodes, by deploying a malicious image.
CVE-2026-66787 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 8.7 High
A flaw was found in the lighthouse component of Red Hat Advanced Cluster Management for Kubernetes. This vulnerability stems from insufficient validation of advertised IP addresses within EndpointSlice objects. A compromised spoke cluster can exploit this by creating EndpointSlices with attacker-controlled IP addresses, causing other clusters' lighthouse DNS to redirect legitimate service traffic to malicious endpoints. This enables a remote attacker to conduct transparent Man-in-the-Middle (MITM) attacks on cross-cluster service communications, potentially leading to unauthorized information disclosure and data manipulation.
CVE-2026-66788 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 9.9 Critical
A flaw was found in Lighthouse. A remote attacker, by compromising a spoke cluster, can exploit a vulnerability where the destination namespace for resource injection is derived from an attacker-controlled label or annotation on the broker object. This allows the attacker to inject unauthorized EndpointSlices and ServiceImports into any namespace on peer clusters, including critical system namespaces like kube-system and openshift-*. This could lead to privilege escalation or other forms of system compromise within the cluster.
CVE-2026-11332 1 Redhat 14 Acm, Ansible Automation Platform, Ansible Automation Platform Developer and 11 more 2026-08-19 7.8 High
A flaw was found in ansible-core. The ansible-galaxy role install command processes dependency specifications from a role's meta/requirements.yml file. Due to improper neutralization of argument delimiters, a malicious role author can inject arbitrary git configuration flags through the src field. This allows arbitrary code execution on the machine of a user who installs the role via ansible-galaxy role install.
CVE-2023-44487 33 Akka, Amazon, Apache and 30 more 378 Http Server, Opensearch Data Prepper, Apisix and 375 more 2026-08-11 7.5 High
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
