{"id":"CVE-2026-32637","summary":"Velero vulnerable to file path traversal when extracting from backup's tarball","details":"Velero is an open source tool for backing up, restoring, and migrating Kubernetes cluster resources and persistent volumes. Prior to 1.18.1, an attacker who compromises the backup object-storage backend can upload a malicious backup tarball containing parent-directory paths that escape the extraction directory during restore and overwrite sensitive files in the Velero pod filesystem. This issue is fixed in version 1.18.1.","aliases":["GHSA-j2g6-362q-6qc6","GO-2026-6259"],"modified":"2026-09-11T03:30:33.721946628Z","published":"2026-08-25T21:15:31.881Z","related":["openSUSE-SU-2026:21761-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32637.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32637.json"},{"type":"ADVISORY","url":"https://github.com/velero-io/velero/security/advisories/GHSA-j2g6-362q-6qc6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32637"},{"type":"REPORT","url":"https://github.com/securego/gosec/issues/324"},{"type":"FIX","url":"https://github.com/velero-io/velero/commit/3f8e3588496391979915ace065f732a9013c1cf0"},{"type":"FIX","url":"https://github.com/velero-io/velero/commit/c7fa4bfe3571667e9731f3f504da3c6be709a24c"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/velero-io/velero","events":[{"introduced":"0"},{"fixed":"3f8e3588496391979915ace065f732a9013c1cf0"},{"fixed":"c7fa4bfe3571667e9731f3f504da3c6be709a24c"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.18.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.18.0-rc.2","v1.18.0","v1.18.0-rc.1","v1.10.0-rc.1","v1.9.0-rc.2","v1.7.0-rc.1","v1.6.0","v1.6.0-rc.2","v1.6.0-rc.1","v1.5.1","v1.5.0-rc.1","v1.5.0-beta.1","v1.4.0","v1.4.0-beta.1","v1.3.0","v1.3.0-beta.2","v1.3.0-beta.1","v1.2.0","v1.2.0-beta.1","v1.1.0","v1.1.0-beta.2","v1.1.0-beta.1","v1.0.0","v1.0.0-rc.1","v1.0.0-beta.1","v1.0.0-alpha.2","v0.11.0","v1.0.0-alpha.1","v0.10.1","v0.10.0","v0.10.0-beta.1","v0.9.0","v0.9.0-alpha.3","v0.9.0-alpha.2","v0.9.0-alpha.1","v0.8.1","v0.8.0","v0.8.0-rc.1","v0.7.1","v0.7.0","v0.6.0","v0.5.0","v0.4.0","v0.3.3","v0.3.2","v0.3.1","v0.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32637.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
