A container escape flaw involving the NVIDIA Container Toolkit could have enabled a threat actor to access AI datasets across tenants.

### Background The [`VOLUME`](https://docs.docker.com/reference/dockerfile/#volume) directive in Dockerfiles, or the [`config.volumes`](https://github.com/opencontainers/image-spec/blob/06e6b47e2ef69021d9f9bf2cfa5fe43a7e010c81/config.md?plain=1#L168-L170) field in OCI image descriptors, indicates filesystem paths "where the process is likely to write data". While these paths have special semantics in Docker, they are only hints in the OCI spec and are not treated specially by Kubernetes. However, containered implements the [specified conversion logic](https://github.com/opencontainers/image-spec/blob/06e6b47e2ef69021d9f9bf2cfa5fe43a7e010c81/conversion.md?plain=1#L100-L105) and adds a mount point if there is none set by Kubernetes. Unfortunately, the specification leaves it open whether the mount point is populated with any and what data, so the runtime needs to be able to push arbitrary data to the Kata agent. However, this is almost always not what the user wants: 1. A declared `VO...

### Summary A command injection vulnerability exists in the `mcp-server-kubernetes` MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.execSync`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.). ### Details The MCP Server exposes tools (`kubectl_scale`, `kubectl_patch` , `explain_resource`, etc) to perform several kubernetes operations. An MCP Client can be instructed to execute additional actions for example via prompt injection when asked to read pod logs. Below some example of vulnerable code and different ways to test this vulnerability including a real example of indirect prompt injection that can lead to ...

A flaw was found in Infinispan CLI. A sensitive password, decoded from a Base64-encoded Kubernetes secret, is processed in plaintext and included in a command string that may expose the data in an error message when a command is not found.

Security continues to be a top priority for organizations managing Kubernetes clusters. Red Hat has made significant strides for improved security for containers with its latest release of Red Hat Advanced Cluster Security 4.8. This release focuses on simplifying management, enhancing workflows and offering visibility into the security of containerized environments.External IP visibility for improved securityRed Hat Advanced Cluster Security 4.8 introduces the general availability of a powerful new feature: The ability to visualize external IPs directly within the network graph dashboard. This

A vulnerability exists in the NodeRestriction admission controller where nodes can bypass dynamic resource allocation authorization checks. When the DynamicResourceAllocation feature gate is enabled, the controller properly validates resource claim statuses during pod status updates but fails to perform equivalent validation during pod creation. This allows a compromised node to create mirror pods that access unauthorized dynamic resources, potentially leading to privilege escalation.

Making sure your Kubernetes environment is secure and compliant is a critical, ongoing challenge, especially for enterprise workloads in the hybrid cloud. To help you meet security requirements with greater confidence and efficiency, we’ve just rolled out key updates to Red Hat Advanced Cluster Security for Kubernetes Cloud Service. This latest release helps significantly strengthen your security posture with newly added industry-standard certifications, including ISO 27001 and PCI DSS 4.0, and deeper integration with key AWS services. These enhancements are designed to streamline compliance

Grab a large sweet tea or a cup of coffee and read the 2024 Product Security Risk Report from Red Hat Product Security. As someone striving to stay informed about the open source ecosystem and its security challenges, I found this year's report noticeably longer, but the depth and detail didn’t disappoint. In fact, one notable addition to this year’s report is the discussion of AI. The numbers game: up, up, and...wait, what?First, let’s break down the raw numbers. Red Hat Security Advisories (RHSA) hit a new peak in 2024, clocking in at 2975. There has been a steady increase over the pa

Many organizations face challenges in creating value from data while maintaining strict regulatory standards set for handling sensitive data. For these organizations, handling large, complex data sets while maintaining efficiency, security and scalability becomes paramount to their deployment. The collaboration between Red Hat and Cloudera offers customers a solution that helps organizations to manage the complete data lifecycle, putting data to work faster and reducing time to value. With Cloudera Private Cloud on Red Hat OpenShift, organizations get aggregated and visualized data that can he

### Impact This vulnerability allows an attacker to perform arbitrary actions on behalf of the victim via the API, such as creating, modifying, and deleting Kubernetes resources. Due to the improper filtering of URL protocols in the repository page, an attacker can achieve cross-site scripting with permission to edit the repository. In `ui/src/app/shared/components/urls.ts`, the following code exists to parse the repository URL. https://github.com/argoproj/argo-cd/blob/0ae5882d5ae9fe88efc51f65ca8543fb8c3a0aa1/ui/src/app/shared/components/urls.ts#L14-L26 Since this code doesn't validate the protocol of repository URLs, it's possible to inject `javascript:` URLs here. https://github.com/argoproj/argo-cd/blob/0ae5882d5ae9fe88efc51f65ca8543fb8c3a0aa1/ui/src/app/shared/components/repo.tsx#L5-L7 As the return value of this function is used in the `href` attribute of the `a` tag, it's possible to achieve cross-site scripting by using `javascript:` URLs. Browsers may return the proper ho...
