Scanning, mitigation and patch-around guidance for Kubernetes 1.25 when the vendor no longer ships fixes.
Compliance Maintenance
Procedure review, controls evidence and the documentation auditors ask for — maintained continuously, not scrambled at audit time.
24/7 Expert Support
Engineers who know this release monitor, manage and fix issues around the clock — break/fix to managed operations.
Kubernetes 1.25 Support: Frequently Asked Questions
Is the Kubernetes 1.25 still supported?
Kubernetes ended support for the Kubernetes 1.25 on Oct 27, 2023 — no more patches or fixes from the vendor. Third-party support keeps it covered: our engineers manage issues, remediate vulnerabilities, and help you maintain compliance for as long as you run it.
When is the Kubernetes 1.25 end of service life (EOSL) date?
Kubernetes lists the end of service life for the Kubernetes 1.25 as Oct 27, 2023.
Can I keep using the Kubernetes 1.25 after its EOSL date?
Yes. EOSL means Kubernetes stops issuing patches and support — the software itself keeps running. Third-party support covers it from there: issue management, security vulnerability remediation, and the compliance documentation auditors ask for, for as long as you choose to run it.
How much does third-party support for the Kubernetes 1.25 cost?
Typically 40-70% below the OEM maintenance renewal price. Exact pricing depends on quantity, service level and location — request a quote and we respond within 24 hours.
Known Vulnerabilities Affecting Kubernetes 1.25
15 published CVEs affect the Kubernetes 1.25, including 6 rated critical or high severity. Kubernetes no longer ships security patches for this release — our engineers provide mitigation guidance, workarounds and hardening support.
| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2016-1906 | CRITICAL | 9.8 | Feb 3, 2016 | Openshift allows remote attackers to gain privileges by updating a build configuration that was created with an allowed type to a type that is not allowed. |
| CVE-2023-3955 | HIGH | 8.8 | Oct 31, 2023 | A security issue was discovered in Kubernetes where a user that can create pods on Windows nodes may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they include Windows nodes. |
| CVE-2023-3676 | HIGH | 8.8 | Oct 31, 2023 | A security issue was discovered in Kubernetes where a user that can create pods on Windows nodes may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they include Windows nodes. |
| CVE-2016-1905 | HIGH | 7.7 | Feb 3, 2016 | The API server in Kubernetes does not properly check admission control, which allows remote authenticated users to access additional resources via a crafted patched object. |
| CVE-2016-7075 | HIGH | 7.5 | Sep 10, 2018 | It was found that Kubernetes as used by Openshift Enterprise 3 did not correctly validate X.509 client intermediate certificate host name fields. An attacker could use this flaw to bypass authentication requirements by using a specially crafted X.509 certificate. |
| CVE-2023-5528 | HIGH | 7.2 | Nov 14, 2023 | A security issue was discovered in Kubernetes where a user that can create pods and persistent volumes on Windows nodes may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they are using an in-tree storage plugin for Windows nodes. |
| CVE-2022-3294 | MEDIUM | 6.6 | Mar 1, 2023 | Users may have access to secure endpoints in the control plane network. Kubernetes clusters are only affected if an untrusted user can modify Node objects and send proxy requests to them. Kubernetes supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. B |
| CVE-2023-2728 | MEDIUM | 6.5 | Jul 3, 2023 | Users may be able to launch containers that bypass the mountable secrets policy enforced by the ServiceAccount admission plugin when using ephemeral containers. The policy ensures pods running with a service account may only reference secrets specified in the service account’s secrets field. Kubernetes clusters are only affected if the ServiceAccount admission plugin and the `kubernetes.io/enforce-mountable-secrets` annotation are used together with ephemeral containers. |
| CVE-2023-2727 | MEDIUM | 6.5 | Jul 3, 2023 | Users may be able to launch containers using images that are restricted by ImagePolicyWebhook when using ephemeral containers. Kubernetes clusters are only affected if the ImagePolicyWebhook admission plugin is used together with ephemeral containers. |
| CVE-2022-3162 | MEDIUM | 6.5 | Mar 1, 2023 | Users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different type in the same API group without authorization. Clusters are impacted by this vulnerability if all of the following are true: 1. There are 2+ CustomResourceDefinitions sharing the same API group 2. Users have cluster-wide list or watch authorization on one of those custom resources. 3. The same users are not authorized to read another custom resource in the same API gr |
| CVE-2020-8554 | MEDIUM | 6.3 | Jan 21, 2021 | Kubernetes API server in all versions allow an attacker who is able to create a ClusterIP service and set the spec.externalIPs field, to intercept traffic to that IP address. Additionally, an attacker who is able to patch the status (which is considered a privileged operation and should not typically be granted to users) of a LoadBalancer service can set the status.loadBalancer.ingress.ip to similar effect. |
| CVE-2023-2431 | LOW | 3.4 | Jun 16, 2023 | A security issue was discovered in Kubelet that allows pods to bypass the seccomp profile enforcement. Pods that use localhost type for seccomp profile but specify an empty profile field, are affected by this issue. In this scenario, this vulnerability allows the pod to run in unconfined (seccomp disabled) mode. This bug affects Kubelet. |
| CVE-2021-25740 | LOW | 3.1 | Sep 20, 2021 | A security issue was discovered with Kubernetes that could enable users to send network traffic to locations they would otherwise not have access to via a confused deputy attack. |
| CVE-2015-7561 | LOW | 3.1 | Aug 7, 2017 | Kubernetes in OpenShift3 allows remote authenticated users to use the private images of other users should they know the name of said image. |
| CVE-2021-25743 | LOW | 3.0 | Jan 7, 2022 | kubectl does not neutralize escape, meta or control sequences contained in the raw data it outputs to a terminal. This includes but is not limited to the unstructured string fields in objects such as Events. |
