{"cve":"CVE-2026-50195","nvd":{"published":"2026-07-01T19:16:53.333","modified":"2026-07-02T19:43:59.417","status":"Analyzed","description":"containerd is an open-source container runtime. Versions prior to 2.3.2, 2.2.5 and 2.1.9 contain a vulnerability in the CRI checkpoint import process where it fails to validate the image references specified within a checkpoint image's configuration. An attacker with permissions to create pods can use a crafted checkpoint image to force containerd to pull a malicious image and assign it an arbitrary local tag, thereby poisoning the node's local image cache. Subsequently, if other pods on the same node attempt to use the poisoned tag with an IfNotPresent (or Never) pull policy, they will unknowingly execute the attacker's malicious image instead of the legitimate one. This can lead to a compromise of the affected pods, allowing the attacker to execute arbitrary code under the victim pod's identity. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:H/SI:H/SA:L","score":5.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-345","CWE-829"],"references":["https://github.com/containerd/containerd/security/advisories/GHSA-cvxm-645q-p574"],"products":["linuxfoundation:containerd"],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-50195","score":0.00303,"percentile":0.23137,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cvxm-645q-p574","url":"https://osv.dev/vulnerability/GHSA-cvxm-645q-p574","summary":"containerd: CRI checkpoint import allows local image tag poisoning","modified":"2026-09-10T03:50:49.278604217Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.1.0 <2.1.9"],"fixed":["2.1.9"]},{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.2.0 <2.2.5"],"fixed":["2.2.5"]},{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.3.0 <2.3.2"],"fixed":["2.3.2"]}]},{"id":"GO-2026-5338","url":"https://osv.dev/vulnerability/GO-2026-5338","summary":"containerd: CRI checkpoint import allows local image tag poisoning in github.com/containerd/containerd","modified":"2026-06-26T15:44:22.793783834Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.1.0 <2.1.9",">=2.2.0 <2.2.5",">=2.3.0 <2.3.2"],"fixed":["2.1.9","2.2.5","2.3.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
