From RELEASE.2022-07-24T01-54-52Z to before RELEASE.2026-04-14T21-32-45Z, A path traversal vulnerability in MinIO's ReadMultiple internode storage-REST endpoint allows a caller holding the cluster root JWT to read files from outside the configured drive roots, bounded only by the MinIO process UID. The attacker sends POST minio/storage/{drivePath}/v63/rmpl with a msgpack-encoded body carrying ../ sequences in the Bucket field. The server opens the resulting path via os.OpenFile with O_RDONLY|O_NOATIME and returns its contents in the msgpack response stream. This vulnerability is fixed in RELEASE.2026-04-14T21-32-45Z.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","score":4.9},"cwes":["CWE-22"],"references":["https://github.com/minio/minio/security/advisories/GHSA-xh8f-g2qw-gcm7"],"products":["minio:minio"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-42600","score":0.08695,"percentile":0.95131,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xh8f-g2qw-gcm7","url":"https://osv.dev/vulnerability/GHSA-xh8f-g2qw-gcm7","summary":"MinIO vulnerable to Path Traversal via msgpack Body in `ReadMultiple` Storage-REST Endpoint","modified":"2026-10-08T08:11:01.361068892Z","packages":[{"ecosystem":"Go","name":"github.com/minio/minio","purl":"pkg:golang/github.com/minio/minio","ranges":[">=0.0.0-20220724015452 <0.0.0-20260414213245"],"fixed":["0.0.0-20260414213245"]}]},{"id":"GO-2026-5757","url":"https://osv.dev/vulnerability/GO-2026-5757","summary":"MinIO vulnerable to Path Traversal via msgpack Body in `ReadMultiple` Storage-REST Endpoint in github.com/minio/minio","modified":"2026-10-08T08:11:01.361068892Z","packages":[{"ecosystem":"Go","name":"github.com/minio/minio","purl":"pkg:golang/github.com/minio/minio","ranges":["all versions"],"fixed":[]}]}],"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).
