CVE-2026-66878

Описание

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.

Отчет

This Important flaw in Red Hat Advanced Cluster Management allows a malicious namespace administrator to exfiltrate sensitive Secret data from other namespaces within the cluster. The vulnerability arises from the multicloud-operators-subscription component incorrectly honoring tenant-controlled namespace references when fetching and copying Secret contents, leading to unauthorized information disclosure. This impacts environments where untrusted namespace administrators have permissions to create Channel and Subscription resources.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
