CVE-2026-53488
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk10th percentile — higher than 10% of all known CVEs
Summary
The CRI plugin in containerd prior to versions 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10 propagates labels from an image config (LABEL instruction in Dockerfile) to a container without validation. This may allow arbitrary command execution on the host via a plugin that consumes container labels for operations.
Risk Assessment
An attacker can exploit this vulnerability to achieve remote code execution on the host, leading to full system compromise and potential takeover of the container environment.
Recommendation
Immediately update containerd to version 1.7.33, 2.3.2, 2.2.5, 2.1.9, or 2.0.10 depending on the branch in use.
Original NVD description (English source)
containerd is an open-source container runtime. In versions prior to 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10 the CRI plugin propagates labels from an image config (LABEL instruction in Dockerfile) to a container without validation. This may result in executing an arbitrary command on the host, via a plugin that consumes container labels for some operations. This issue has been fixed in versions 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10.
