Server file disclosure via update URL fallback
Published Aug 1, 2022 · Updated Apr 22, 2025
Path traversal in MinIO before RELEASE.2022-07-29T19-40-48Z allows remote authenticated users to read server files through the update API. The downloadReleaseURL function in cmd/update.go treats a non-HTTP update URL as a filesystem path, opens it directly, and returns the file content inside an error response. Access requires an admin identity authorized for admin:ServerUpdate, and disclosure is limited to paths readable by the MinIO process.
