CVE-2026-71846 Medium · 6.5 CWE-250 Aug 12, 2026

Insights-client: insights-client: clusterrole grants cluster-wide secrets get/list/watch beyond least privilege

A flaw was found in insights-client. The component's ServiceAccount is bound to a ClusterRole granting cluster-wide secrets get, list, and watch permissions, while the code only requires access to a single specific Secret. This excessive privilege means that a compromise of the insights-client pod or ServiceAccount token would grant an attacker read access to all Secrets across the hub cluster, including managed-cluster kubeconfigs and other sensitive credentials.

CVE-2026-71845 High · 7.7 CWE-532 Aug 11, 2026

Insights-client: insights-client: ccx_token bearer credential logged in clear text at startup via setdefault()

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.

CVE-2026-71475 Medium · 6.8 CWE-22 Aug 11, 2026

Insights-client-rhel9: insights-client: spoke-controlled clusterid injected unencoded into insights api url path

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.

CVE-2026-71474 High · 7.1 CWE-532 Aug 11, 2026

Insights-client-rhel9: insights-client: pull-secret bearer token written to logs on non-200 ccx response

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.

CVE-2026-44495 High · 7.7 CWE-94 Jun 11, 2026

Axios: Credential Theft and Response Hijacking via Prototype Pollution Gadget in Config Merge

Axios is a promise based HTTP client for the browser and Node.js. From 0.19.0 to before 0.31.1 and 1.15.2, Axios contains prototype-pollution gadgets in request config processing. If another vulnerability in the same JavaScript process has already polluted Object.prototype.transformResponse, affected Axios versions may treat that inherited value as request configuration or as an option validator. Axios does not itself create the prototype pollution. Exploitability requires a separate prototype-pollution vulnerability or equivalent attacker control over Object.prototype before Axios creates a request. This vulnerability is fixed in 0.31.1 and 1.15.2.

CVE-2025-57851 Medium · 6.7 CWE-276 Apr 8, 2026

Mce: privilege escalation via excessive /etc/passwd permissions

A container privilege escalation flaw was found in certain Multicluster Engine for Kubernetes images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.

CVE-2026-4740 High · 8.2 CWE-295 Apr 7, 2026

Rhacm: open cluster management (ocm): cross-cluster privilege escalation via improper kubernetes client certificate renewal validation

A flaw was found in Open Cluster Management (OCM), the technology underlying Red Hat Advanced Cluster Management (ACM). Improper validation of Kubernetes client certificate renewal allows a managed cluster administrator to forge a client certificate that can be approved by the OCM controller. This enables cross-cluster privilege escalation and may allow an attacker to gain control over other managed clusters, including the hub cluster.

CVE-2025-14874 High · 7.5 CWE-703 Dec 18, 2025

Nodemailer: nodemailer: denial of service via crafted email address header

A flaw was found in Nodemailer. This vulnerability allows a denial of service (DoS) via a crafted email address header that triggers infinite recursion in the address parser.

CVE-2023-44487 High · 7.5 KEV Urgent · 73 Public exploit CWE-400 Oct 10, 2023

HTTP/2 Rapid Reset Attack Vulnerability

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.
