Zip files containing archive members with maliciously crafted names (e.g., `../../../../etc/password`) can be written to arbitrary locations on the filesystem when an administrator restores the archive as a compressed etcd snapshot.\n\n#### Mitigations\n\n* Enable golang's built-in [insecure path protections](https://pkg.go.dev/archive/zip#NewReader) when restoring snapshots by setting the`GODEBUG` environment variable:\n    ```bash\n    GODEBUG=zipinsecurepath=0 k3s server --cluster-reset --cluster-reset-restore-path=/path/to/snapshot.zip\n    ```\n* Manually extract the snapshot from the zip archive before restoring it. If the snapshot to be restored does not end with `.zip`, the vulnerable extraction code will not be executed.\n\n#### Additional Notes\n\nAdministrators should be aware of the cautions noted in the \"Security\" section of the documentation on [Restoring Snapshots](https://docs.k3s.io/cli/etcd-snapshot#security).","state":0,"publishedAt":"2026-07-14T17:54:14+00:00","modifiedAt":"2026-09-10T03:50:52.5660367+00:00","affected":[{"ecosystem":"Go","name":"github.com/k3s-io/k3s","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"1.35.0-rc1"},{"kind":"fixed","version":"1.35.3"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/k3s-io/k3s","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"1.34.0-rc1"},{"kind":"fixed","version":"1.34.6"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/k3s-io/k3s","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.33.10"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/k3s-io/k3s/security/advisories/GHSA-jxr7-mqhw-9p98","https://nvd.nist.gov/vuln/detail/CVE-2026-54250","https://github.com/k3s-io/k3s"],"sourceUrl":"https://github.com/advisories/GHSA-jxr7-mqhw-9p98","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-jxr7-mqhw-9p98","identifiers":["GHSA-jxr7-mqhw-9p98","CVE-2026-54250","GO-2026-5973"]},"retained":false,"historicalAffected":[]},{"revision":"bbdd59e6ba6248dd90cae608a1ffbdde","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-5973","aliases":["CVE-2026-54250","GHSA-jxr7-mqhw-9p98"],"title":"K3s: ZIP Archive Path Traversal Vulnerability in etcd Snapshot Decompression in github.com/k3s-io/k3s","description":"K3s: ZIP Archive Path Traversal Vulnerability in etcd Snapshot Decompression in github.com/k3s-io/k3s.\n\nNOTE: The source advisory for this report contains additional versions that could not be automatically mapped to standard Go module versions.\n\n(If this is causing false-positive reports from vulnerability scanners, please suggest an edit to the report.)\n\nThe additional affected modules and versions are: github.com/k3s-io/k3s before v1.33.10, from v1.34.0-rc1 before v1.34.6, from v1.35.0-rc1 before v1.35.3.","state":0,"publishedAt":"2026-07-17T19:42:05+00:00","modifiedAt":"2026-07-28T21:00:01.782495+00:00","affected":[{"ecosystem":"Go","name":"github.com/k3s-io/k3s","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/k3s-io/k3s/security/advisories/GHSA-jxr7-mqhw-9p98","https://nvd.nist.gov/vuln/detail/CVE-2026-54250"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-5973","license":"OSV · upstream source license applies","key":"osv:GO-2026-5973","identifiers":["GO-2026-5973","CVE-2026-54250","GHSA-jxr7-mqhw-9p98"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
