CVE-2026-71845 Alta · 7.7 CWE-532 11/08/2026

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-2026-71474 Alta · 7.1 CWE-532 11/08/2026

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-2026-71468 Média · 5.3 CWE-266 11/08/2026

Acm-search-v2-api-rhel9: search-v2-api: cross-user bearer-token reuse via global federation-config cache

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.

CVE-2026-10090 Crítica · 9.0 CWE-267 05/08/2026

Multicluster-operators-subscription: multicluster-operators-subscription: namespace edit user can deploy cluster-scoped clusterrolebinding and become cluster-admin via application subscription

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.
