CVE-2026-53489

MEDIUM

containerd: Arbitrary host CRI log file read via symlink following in CRI checkpoint restore

Title source: cna
STIX 2.1

Description

containerd is an open-source container runtime. Versions prior to 2.3.2, 2.2.5 and 2.1.9 contain a bug where the CRI plugin restores container.log from a checkpoint image without validating a symlinked path. This could result in reading an arbitrary file on the host via kubectl logs. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.
