Who is impacted?_\nIf the attacker compromises the backup's object storage backend and uploads a malicious backup tarball including file names like the following:\n* ../../../tmp/escape_1              -> file created at /tmp/escape_1\n* ../../../../../../../../tmp/escape_2 -> file created at /tmp/escape_2\n* ../../../tmp/cron_poc              -> would be /etc/cron.d/backdoor in real attack\n* ../../../tmp/ssh_poc               -> would be ~/.ssh/authorized_keys\n* ../../../tmp/kubeconfig_poc        -> would be ~/.kube/config\n\nIt's possible that extracting files from the tarball during restore can overwrite sensitive files in the Velero pod filesystem. \n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\nBy far, there is no patch yet.\nWe are working on the main branch, then cherry-pick to the release-1.18 for v1.18.1 patch.\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\nThere is no workaround, but the good news is that keeping your OSS safe will prevent the vulnerability.","state":0,"publishedAt":"2026-08-20T17:26:07+00:00","modifiedAt":"2026-09-10T03:50:53.7172599+00:00","affected":[{"ecosystem":"Go","name":"github.com/vmware-tanzu/velero","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.18.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/velero-io/velero/security/advisories/GHSA-j2g6-362q-6qc6","https://github.com/securego/gosec/issues/324","https://github.com/velero-io/velero"],"sourceUrl":"https://github.com/advisories/GHSA-j2g6-362q-6qc6","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-j2g6-362q-6qc6","identifiers":["GHSA-j2g6-362q-6qc6","CVE-2026-32637","GO-2026-6259"]},"retained":false,"historicalAffected":[]},{"revision":"328d9d61d6a7473088e2f52a4cebe7b0","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6259","aliases":["CVE-2026-32637","GHSA-j2g6-362q-6qc6"],"title":"Velero vulnerable to file path traversal when extracting from backup's tarball in github.com/vmware-tanzu/velero","description":"Velero vulnerable to file path traversal when extracting from backup's tarball in github.com/vmware-tanzu/velero","state":0,"publishedAt":"2026-08-25T19:43:10+00:00","modifiedAt":"2026-08-26T01:20:20.550101+00:00","affected":[{"ecosystem":"Go","name":"github.com/vmware-tanzu/velero","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.18.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/velero-io/velero/security/advisories/GHSA-j2g6-362q-6qc6","https://github.com/securego/gosec/issues/324"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6259","license":"OSV · upstream source license applies","key":"osv:GO-2026-6259","identifiers":["GO-2026-6259","CVE-2026-32637","GHSA-j2g6-362q-6qc6"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
