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.","state":0,"publishedAt":"2026-05-11T20:53:10.885+00:00","modifiedAt":"2026-05-15T18:24:49.669+00:00","affected":[{"ecosystem":"Vendor product","name":"minio","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"minio\",\n                    \"product\": \"minio\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= RELEASE.2022-07-24T01-54-52Z, < RELEASE.2026-04-14T21-32-45Z\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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,"severity":"MEDIUM"}],"references":["https://github.com/minio/minio/security/advisories/GHSA-xh8f-g2qw-gcm7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-42600","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-42600","identifiers":["CVE-2026-42600"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
