What is CVE-2026-76061?
CVE-2026-76061 is a medium-severity path traversal vulnerability in Red Hat OpenShift Container Platform 4, published on 6 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
A flaw was found in CRI-O's `bind_mount_prefix` handling. When configured with a non-empty `bind_mount_prefix`, a malicious container or local attacker could use a Container Runtime Interface (CRI) hostPath containing an intermediate absolute symlink. This could cause the bind mount source to resolve outside the intended prefixed root, potentially leading to unauthorized access to files or privilege escalation on the host system.
