CVE-2026-13622: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Red Hat Red Hat OpenShift Virtualization 4CVE-2026-13622 0 CVE-2026-13622 is a symlink following vulnerability in the virt-handler migration proxy component of Red Hat OpenShift Virtualization 4. During live migration, virt-handler dials Unix sockets inside target virt-launcher pods via /proc/<pid>/root/ paths without symlink protection. An attacker with namespace edit and pods/exec permissions can replace a migration proxy socket with a symlink to the host CRI-O socket, enabling full node compromise due to virt-handler running as root in the host mount namespace. Exploitation requires authenticated user permissions typical for VM operators. The vulnerability allows container-to-host escape and complete node compromise by relaying attacker-controlled data to the container runtime. Red Hat rates this vulnerability as important with a CVSS score of 8.8 (high severity). Join the discussion | CVE Database V5 | 08/12/2026, 20:46:15 UTC Added: 08/12/2026, 21:12:16 UTC |
