From 1.16.0 until 1.21.2, 1.22.2, and 1.23.1, the DecompressTarGz function in keadm/cmd/keadm/app/cmd/util/common.go joins archive entry names to the extraction destination without sufficient validation. During keadm join or installation on Windows edge nodes, an archive influenced through a compromised, replaced, or untrusted download source can contain parent-directory components, Windows-style backslashes, absolute paths, or drive-prefixed paths that escape the intended directory. The affected keadm process can consequently write or overwrite files with its own privileges, potentially modifying configuration, executable, or service files and enabling persistent system modification or code execution. This issue is fixed in versions 1.21.2, 1.22.2, and 1.23.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-22"],"references":["https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.21.md","https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.22.md","https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.23.md","https://github.com/kubeedge/kubeedge/commit/47767b7f2649afcfa3a856e87d556f7777e0428d","https://github.com/kubeedge/kubeedge/commit/a524a66a1ae1691eb8ff16b6ff9a93fb370d4047"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-62369","score":0.00633,"percentile":0.50363,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9vm9-pqxx-x83v","url":"https://osv.dev/vulnerability/GHSA-9vm9-pqxx-x83v","summary":"KubeEdge: keadm DecompressTarGz path traversal enables arbitrary file write on Windows during edge node join","modified":"2026-10-01T20:55:52.777452175Z","packages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.16.0 <1.21.2"],"fixed":["1.21.2"]},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.22.0 <1.22.2"],"fixed":["1.22.2"]},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.23.0 <1.23.1"],"fixed":["1.23.1"]}]},{"id":"GO-2026-6563","url":"https://osv.dev/vulnerability/GO-2026-6563","summary":"KubeEdge: keadm DecompressTarGz path traversal enables arbitrary file write on Windows during edge node join in github.com/kubeedge/kubeedge","modified":"2026-10-01T20:45:13.182661403Z","packages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.16.0 <1.21.2",">=1.22.0 <1.22.2",">=1.23.0 <1.23.1"],"fixed":["1.21.2","1.22.2","1.23.1"]}]}],"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).
