GHSA-7JCP-V9W4-WJMG
Vulnerability from github – Published: 2026-05-26 15:32 – Updated: 2026-06-30 18:04A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.

Mitigation MIT-48.1
Strategy: Separation of Privilege
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack
An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
