| CVE-2023-44487 | Hig | 0.65 | 7.5 | 1.00 | KEV | Oct 10, 2023 | 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. | |
| CVE-2026-10090 | Cri | 0.59 | 9.0 | 0.00 | Aug 5, 2026 | 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… | ||
| CVE-2026-17107 | Hig | 0.55 | 8.5 | 0.00 | Jul 24, 2026 | A flaw was found in the cluster-proxy service-proxy component used in Red Hat Advanced Cluster Management for Kubernetes (RHACM) and multicluster-engine (MCE). The service-proxy appends impersonation group headers to proxied requests without first removing caller-supplied… | ||
| CVE-2023-3027 | Hig | 0.51 | 7.8 | 0.00 | Jun 5, 2023 | The grc-policy-propagator allows security escalation within the cluster. The propagator allows policies which contain some dynamically obtained values (instead of the policy apply a static manifest on a managed cluster) of taking advantage of cluster scoped access in a created… | ||
| CVE-2022-3841 | Hig | 0.51 | 7.8 | 0.00 | Jan 13, 2023 | RHACM: unauthenticated SSRF in console API endpoint. A Server-Side Request Forgery (SSRF) vulnerability was found in the console API endpoint from Red Hat Advanced Cluster Management for Kubernetes (RHACM). An attacker could take advantage of this as the console API endpoint is… | ||
| CVE-2022-27191 | Hig | 0.49 | 7.5 | 0.04 | Mar 18, 2022 | The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to crash a server in certain circumstances involving AddHostKey. | ||
| CVE-2026-4740 | Hig | 0.46 | 8.2 | 0.00 | Apr 7, 2026 | 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… | ||
| CVE-2025-57851 | Med | 0.42 | 6.4 | 0.00 | Apr 8, 2026 | 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… | ||
| CVE-2025-14874 | Hig | 0.42 | 7.5 | 0.00 | Dec 18, 2025 | 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-2022-2238 | Med | 0.42 | 6.5 | 0.01 | Sep 1, 2022 | A vulnerability was found in the search-api container in Red Hat Advanced Cluster Management for Kubernetes when a query in the search filter gets parsed by the backend. This flaw allows an attacker to craft specific strings containing special characters that lead to crashing… | ||
| CVE-2020-25655 | Med | 0.37 | 5.7 | 0.01 | Nov 9, 2020 | An issue was discovered in ManagedClusterView API, that could allow secrets to be disclosed to users without the correct permissions. Views created for an admin user would be made available for a short time to users with only view permission. In this short time window the user… | ||
| CVE-2025-6017 | Med | 0.36 | 5.5 | 0.00 | Jul 2, 2025 | A flaw was found in Red Hat Advanced Cluster Management through versions 2.10, before 2.10.7, 2.11, before 2.11.4, and 2.12, before 2.12.4. This vulnerability allows an unprivileged user to view confidential managed cluster credentials through the UI. This information should… | ||
| CVE-2022-3248 | Med | 0.29 | 4.4 | 0.00 | Oct 5, 2023 | A flaw was found in OpenShift API, as admission checks do not enforce "custom-host" permissions. This issue could allow an attacker to violate the boundaries, as permissions will not be applied. | ||
| CVE-2020-25688 | Low | 0.23 | 3.5 | 0.00 | Nov 23, 2020 | A flaw was found in rhacm versions before 2.0.5 and before 2.1.0. Two internal service APIs were incorrectly provisioned using a test certificate from the source repository. This would result in all installations using the same certificates. If an attacker could observe network… |
